Optical Design
The company provides optical design service which includes lens, mechanics, and thin film coating. Customers are welcome to discuss the various specifications before placing the order or can simply place the order if specifications are all well defined. Our final design would include system analysis, prescription details plus a set of drawings following ISO standard.
​
Zemax design software is used for lens design and optical system analysis such as spot diagrams, MTF, tolerance, relative illumination etc. For coating design, Film*Key is used.
Successful designs including the followings:
​
Modulation Transfer Function [MTF]
-
Laser Rangefinder system which involves a 4x telescope system for visible spectrum and focusing lenses for IR laser diode (850nm).
-
Teleconferencing camera and overhead projector zoom lens: camera is placed on top of a computer that can capture an A4 paper with high resolution of 100 lp/mm, the transmitted image is projected onto a screen (range from 10 to 40 feet) using the projector zoom lens.
-
Night vision 6x objective lens F/2.0 which takes in near infra-red wavelength and has a variable zoom. Modulation transfer function (MTF) is 20% for the full field at 100 lp/mm.
-
Biomedical objective F/1.8 that accepts image from an image intensifier tube (Photopic wavelength) and projects for far distance viewing.
