Mainstream software commonly used by optical designers includes these: TRACEPRO, LIGHTTOOLS, LUCIDSHAPE, UG. 
The housewife thinks that the lamp is an ornament. The architect engineer thinks that the lamp is a building material, but the essence of the lamp is the light after being lit, so the design of the lamp, the industrial, the heat dissipation, the most essential is the optical design. . In the era of traditional light sources, optical design is a matter of height, but in the LED era, optical design began to push from the application field, optical design in lamps has become more and more needed, then what do you need to do optical design? software? Let's go to science today.
TRACEPRO
This software makes optical design functions relatively simple, can be easily modeled, and do basic optical tracking! Suitable for beginners. There is no advanced automatic optimization.

LIGHTTOOLS
This software uses more people. It is fast, not just analysis software, but design software.
Figure: LIGHTTOOLS operator interface.
The biggest advantage of LIGHTTOOLS is that it has excellent automatic optimization functions in addition to basic lighting system modeling and simulation. Various standard formats can also be supported, such as STEP, SAT, IGES, CATIA, and the like.

LUCIDSHAPE (German Light of Germany)
Hella Light is a powerful 3D optical design software for computer-aided design of lighting and optical products.
Direct support for digital-to-analog formats igs, 3dm, stp. Direct support for optical format ies, krs (OPTRONIK format), lmt (LMT company format), and other manufacturers of optical format, asap format, light file format. Support interoperability with CATIA and rhinoceros, super cow!

UG
What should I do when the optics are done? To do the structural design! After the structure is made, the model map and the mold map can be generated, and then the mold production is started. At this time, 3D software UG will be used.
Figure: After the optical model is built, the structure is a complete optical device.
to sum up
A relatively simple design such as a lens and a reflector is generally versatile with LIGHTTOOLS. If you want to design complex optical components such as the high standard European standard low beam optical system, you need to use powerful software such as LUCIDSHAPE.
