Physics / Optics Graduation Internship: New Optical Sensor Concepts

Optical engineering


In a nutshell


Veldhoven, Netherlands


No experience (Student)



Job Category

Optical engineering, Physics


Are you a Master student in Physics or Optical Engineering with a strong interest in Optical Design? Then this graduation internship could be interesting for you!

Job Mission

ASML produces photolithography scanners performing with nanometer accuracy at a very high speed. This is achieved thanks to several elements: good design, very accurate sensors, and clever algorithms. We constantly seek improvements in all these elements to improve scanner performance. In being part of ASML, your task is to push this boundary of accuracy and speed beyond the current status by exploring new optical sensor designs.

Job Description

For years, our level sensors have been very successful in measuring wafer thickness variations and generating wafer height maps. These wafer height maps are used for active focusing of the scanner projection optics and are thus critical to a scanner’s performance. In order to make our machines affordable to more customers we aim to reduce the cost of our level sensors without sacrificing their performance.

You will investigate new optical design concepts for the level sensor and its submodules with the aim to reduce the complexity and cost of the sensor while maintaining its performance.


You are a Master student in Physics, Optical Engineering or a related field. You are keen to learn about optical design, imaging aberration theory and optical technology. Experience in optical ray tracing programs (e.g. Zemax OpticStudio, Code V or OSLO) is welcome but not a necessity.

This is a Master graduation internship for 5 days a week with duration of minimum 9 months. The start date is as soon as possible.

Please keep in mind that we can only consider students (who are enrolled at a school during the whole internship period) for our internships and graduation assignments.

Other information

What ASML offers
Your internship will be in one of the leading Dutch corporations, gaining valuable experience in a highly dynamic environment. You will receive a monthly internship allowance based on your educational level and number of days per week, plus a possible housing or travel allowance. More information on the allowances can be found on our website. In addition you will get expert, practical guidance and the chance to work in and experience a dynamic, innovative team environment.

ASML: Be part of progress
We make machines that make chips – the hearts of the devices that keep us informed, entertained and safe; that improve our quality of life and help to tackle the world’s toughest problems.

We build some of the most amazing machines that you will ever see, and the applications to run them. Never satisfied, we measure our performance in units that begin with pico or nano.

We believe we can always do better. We believe the winning idea can come from anyone. We love what we do – not because it’s easy, but because it’s hard. At ASML we are always pushing technology further.

Students: Getting ready for the real-world
Teamwork is key within ASML. Our R&D team is more than 5,500 people strong and worldwide we form one big team with over 25,000 employees. These colleagues have 123 different nationalities and work at our major sites on three continents.

Dozens of diverse, interdisciplinary teams work in parallel to meet a challenging development schedule. In this inspiring environment, your colleagues may be sitting next door, or they could be thousands of kilometers away in a different country, or even working for a different company.

An internship at ASML is your opportunity to get to know this world and get a feel for that excites you most. Use your education, gain real-life working experience and explore the world of high-tech – all at the same time.
