Hello everyone,
I'm designing a surgical headlight as a gift for my brother and boy have I gotten myself into a world of hurt.
I've been struggling with understanding how to collimate a Nichia E17A SM573-B12-R9080 @ 5700K
Specs:
I am looking for some insight on a lens or lenses that address the following requirements:
Attached is an example of the beam I am looking for and how the setup will be worn.
So far what I understand is that I need an aspheric lens(es) and my lens angle is about 15 degrees.
How do I find out the specifications of the lens that I need? and do you guys have any recommendations?
Thank you

I've been struggling with understanding how to collimate a Nichia E17A SM573-B12-R9080 @ 5700K
Specs:
- 120 lm output
- 1.7mm x 1.7mm x 0.3mm
- 120 degree
- 5700k
- CRI 90+
I am looking for some insight on a lens or lenses that address the following requirements:
- Circular beam with uniform lighting throughout
- Tight edges with least amount of halo/spill as possible
- Produce a 130mm (diameter) circle from a distance of 500mm
- Maintain colours after collimating
- I want at least 90 lumens after collimation
- This will be attached near the face so weight and lens diameter is a concern.
