DESC9166: Photometry and Colorimetry

Semester 1, 2026 [Block mode] - Camperdown/Darlington, Sydney

Measurements of light based only on physical properties are of limited use to the lighting designer. Instead, the tools to measure and communicate the characteristics of light sources and illumination consider the impact of the physical attributes of light on the human visual system. This unit covers the photometric measures related to the quantity of light and illumination and the colorimetric systems used to characterise the colour of lights and objects. The calculation methods underlying these measures are included, with an emphasis on useful simulation techniques. The derivations, meanings, proper applications, and limitations of these measurements systems are discussed. An overview of physical instruments for photometric and colorimetric measurements is included. Students learn to apply knowledge of photometry and colorimetry to evaluate lighting products.

Assessment summary

 

  • Short Video: For this assignment, you will collaborate with other students in a team. Each group will prepare a video presentation with hand-out material. A self/peer assessment form must be completed on the final day of class. Each student is required to assess the contribution of their group and themselves. Based on the information reported by all team members, members of the same group may receive different marks for this assignment.
  • Applied calculations: For this assignment, you will respond to a fictitious email outlining a situation you might encounter as a lighting designer. You will perform photometric and colorimetric calculations on lighting data to make design decisions.
  • Detailed information for each assessment can be found on Canvas.

Assessment criteria

The University awards common result grades, set out in the Coursework Policy 2021 (Schedule 1).

As a general guide, a high distinction indicates work of an exceptional standard, a distinction an excellent standard, a credit a good standard, and a pass an acceptable standard.

Result name

Mark range

Description

High distinction

Work of excellent quality, demonstrating a sound grasp of the learning outcomes
assessed. The work shows innovation, experimentation, critical analysis,
synthesis, insight, creativity, and/or superior skill.

Credit

65 - 74

Work of good quality, demonstrating more than satisfactory achievement of the
learning outcomes assessed, or work of excellent quality for a majority of the
learning outcomes assessed.

Pass

assessed.

Fail

0 - 49

Work that does not meet the learning outcomes of the unit to a satisfactory standard.

 

For more information see guide to grades.

Use of generative artificial intelligence (AI)

You can use generative AI tools for open assessments. Restrictions on AI use apply to secure, supervised assessments used to confirm if students have met specific learning outcomes.

Refer to the assessment table above to see if AI is allowed, for assessments in this unit and check Canvas for full instructions on assessment tasks and AI use.

If you use AI, you must always acknowledge it. Misusing AI may lead to a breach of the Academic Integrity Policy.

Visit the Current Students website for more information on AI in assessments, including details on how to acknowledge its use.

Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

  • Deduction of 5% of the maximum mark for each calendar day after the due date.
  • After ten calendar days late, a mark of zero will be awarded.

This unit has an exception to the standard University policy or supplementary information has been provided by the unit coordinator. This information is displayed below:

In accordance with University of Sydney School of Architecture Design and Planning Faculty Resolutions 2022, for every calendar day up to and including 10 calendar days after the due date, a penalty of 5% of the maximum awardable marks will be applied to the late work. For work submitted more than 10 calendar days after the due date, a mark of zero will be awarded. No Simple Extensions will be granted for the group assignment.

Academic integrity

The University expects students to act ethically and honestly and will treat all allegations of academic integrity breaches seriously.

Our website provides information on academic integrity and the resources available to all students. This includes advice on how to avoid common breaches of academic integrity. Ensure that you have completed the Academic Honesty Education Module (AHEM) which is mandatory for all commencing coursework students

Penalties for serious breaches can significantly impact your studies and your career after graduation. It is important that you speak with your unit coordinator if you need help with completing assessments.

Visit the Current Students website for more information on AI in assessments, including details on how to acknowledge its use.

Simple extensions

If you encounter a problem submitting your work on time, you may be able to apply for an extension of five calendar days through a simple extension.  The application process will be different depending on the type of assessment and extensions cannot be granted for some assessment types like exams.

Special consideration

If exceptional circumstances mean you can’t complete an assessment, you need consideration for a longer period of time, or if you have essential commitments which impact your performance in an assessment, you may be eligible for special consideration or special arrangements.

Special consideration applications will not be affected by a simple extension application.

Using AI responsibly

Co-created with students, AI in Education includes lots of helpful examples of how students use generative AI tools to support their learning. It explains how generative AI works, the different tools available and how to use them responsibly and productively.

Support for students

The Support for Students Policy reflects the University’s commitment to supporting students in their academic journey and making the University safe for students. It is important that you read and understand this policy so that you are familiar with the range of support services available to you and understand how to engage with them.

The University uses email as its primary source of communication with students who need support under the Support for Students Policy. Make sure you check your University email regularly and respond to any communications received from the University.

Learning resources and detailed information about weekly assessment and learning activities can be accessed via Canvas. It is essential that you visit your unit of study Canvas site to ensure you are up to date with all of your tasks.

If you are having difficulties completing your studies, or are feeling unsure about your progress, we are here to help. You can access the support services offered by the University at any time:

Attendance and class requirements

Please refer to the Resolutions of the University School: University of Sydney School of Architecture Design and Planning Faculty Resolutions 2022 Clause 8 (3) (a). Students are expected to attend a minimum of 90% of timetabled activities for each unit of study, unless granted exemption. Students who do not meet this threshold, and who have approved special consideration may be offered the opportunity to sit an alternative assessment.

 

Study commitment

Typically, there is a minimum expectation of 1.5-2 hours of student effort per week per credit point for units of study offered over a full semester. For a 6 credit point unit, this equates to roughly 120-150 hours of student effort in total.

Learning outcomes are what students know, understand and are able to do on completion of a unit of study. They are aligned with the University's graduate qualities and are assessed as part of the curriculum.

At the completion of this unit, you should be able to:

  • LO1. select and apply photometric and colorimetric calculation procedures to make predictions about the performance of lighting products.
  • LO2. use photometric and colorimetric quantities to inform design decisions.
  • LO3. find and critically evaluate information on novel photometric topics.
  • LO4. collaborate effectively with peers.
  • LO5. communicate effectively about photometry and colorimetry, orally and through writing.
