30° - 60° - 90° Littrow Prisms have two main applications. 1. Uncoated littrow dipersion prisms are used to disperse light into its component spectrum. 2. Coated littrow dipersion prisms are used to deviate the line of sight by 60°.

Made from BK7 material, which has transparent range from 330-2100nm. The refractive index is 1.5168 at 587.6nm. The BK7 window has good performance over visible and near IR spectrum for most application.

Dual Wavelengths Waveplate is a multiple waveplate that provide a specitfic retardance at two different wavelengths Operates as λ/2 @ λ1 & as λ/4 @ λ2 Dual Wavelength Operation 532 nm/1064 nm

Double Convex Lenses, Bi-convex Lenses have two outward curved surfaces, a positive focal length and are useful for 1:1 imaging and in multi-element systems.These lenses are designed to have a focal length of f= (R1*R2)/((n-1)*(R2-R1)) 1. Supported by the Zemax Optical Design Package 2. Posistive Focal Length 3. Material upon requirement
