Definition of Collimated Light
Collimated light is defined as a collimated beam of light rays travelling in parallel to one another and diverges minimally as it proliferates.
The parallel light rays suppress the wraparound of light and enables precise dimension measuring and appearance inspection.
Ways to achieve collimated effect
Firstly, collimated effect can be achieved by using a smaller light unit and this changes the angle on the sample’s surface where the light rays encounter it and creates a well- defined image outline of the sample.
Another technique to obtain collimated light rays is by shifting the light source further from the sample, resulting in a smaller angle of incidence and thus a high degree of collimation if only one size is available.
Lastly, parallelism of light can be attained by placing light control films (horizontal and vertical directions) over the light emitting surface of the light unit.
Attain true collimated light effect
Alternatively, CCS Asia offers highly parallel back and coaxial light namely MFU and MSU Series respectively to help you attain true collimated light to ensure that sharp silhouette image effortlessly. Reach out to us today at [email protected] if you would like to find out more.
