Cemented Doublet- Achromatic Lens
Cemented Doublet- Achromatic Lens
VY Optoelectronics Co. Ltd., China
Glued doublet is an achromatic consisting of a positive low-index crown glass lens element cemented to a negative high-index flint glass lens element. The elements are chosen so as to cancel chromatic aberration at two well-separated wavelengths, usually in the blue and red region of the spectrum. Focal length is constant at those two wavelengths and focal length shifts are virtually eliminated across the visible wavelengths.

Cube Beamsplitters for Food Sorting
Cube Beamsplitters for Food Sorting
Knight Optical, United States
Polarizing beamsplitter cubes are often used within optical sorting systems; how a polarizing beamsplitter cube works by allowing P-polarized light to pass undeviated through the cube while S-polarized light is reflected at 90°. The quality of the cube is typically defined by the extent and accurate beam deviation of the transmitted and reflected polarized light and by the extinction ratio of the cube.

Beamsplitter Cubes
Beamsplitter Cubes
Delta Optical Thin Film A/S, Denmark
We have developed coatings that combine different functions, e.g., separate the incident light by both wavelength and polarization simultaneously, i.e., a smart component that splits p- and s-pol in a limited wavelength range. P-pol is transmitted with a high efficiency while s-polarization is reflected. This smart splitter can be used in detection systems and other systems involving laser light.
