LEDs are the first preference of fiber illumination sources. These have taken place of lasers and arc lamps. The latter two have too many adverse effects associated with them. This doesn’t happen with fiber-coupled LEDs. They have numerous applications in research, educational and scientific world. Why pick Kewlab Fiber coupled LED They are less expensive and are more trustworthy in terms of durability and longevity. Latest fiber coupled LEDs provide a higher level of intensity of light. One such example is >25mW blue light through a 200 micron fiber. Here are the other features of Kewlab LED you should have a look at. The Applications    Kewlab Fiber coupled LED can be utilized for •Transmission/Reflectivity measurement •Spectral analysis and absorption spectrum measurement •Color measurement •Spectral analysis and absorption spectrum measurement •Fluorescence measurement This doesn’t end here: Kewlab Fiber coupled LED has more to offer: It has the abili

Collimating lenses are optical lenses that help in making the light entering into the spectrophotometer parallel. With a collimating lens from Thorlabs or elsewhere, one can control the field of view, spatial resolution of their setup, collection angles for sampling and illumination. Why are they important in the first place? One of the prime reasons for use of the collimating lens is high divergence result of a laser diode. It is made up of aspheric lenses, they do not pose spherical aberration. Collimating lenses are usually picked as and when a collimated beam requirement is between one and five millimetres. Where are they used and how are they used? Collimating lens is placed inside a collimator. An Optical collimator is utilized for calibration, testing and measurement. In one of the types of the collimator, patterns are projected into infinity. When a target is kept in the focal plane of a collimator, the uniform target seems extremely near. This phe
