Also allowed for the phosphorus converted amber (PC Amber). A bit lighter in tone than a regular amber which is very orangy. Thermally stable like a white, losing only 10-15% of its lumen output at operating temps vs the regular amber which would see 50% loss. Game changer for emergency lighting.

I would definitely recommend doing optics as a specialization not the main field. While its growing, its a very nitch field and the employment pool is not as large as the main enginering fields (EE, ME, SW).

I'm a mechanical engineer with a specialization in optics. Having both fields has helped me do better design, but also when optical work is done, I can then move onto the mechanics of things. Helps with finding jobs as you can now target either or.
