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

Custom step windows are ideal use in viewports, pressure, and vacuum situations. Sapphire step windows also make great viewports for deep ocean vehicles.

Plano-Convex Lenses is best used where one conjugate point (object distance S or image distance S' ) is more than five times the other. This lens shape is near best-form for either focusing collimated light or for collimating a point source.

MgF2 windows are used in the UV, visible and IR ranges, with approximately 94% transmission from 200 - 1000 nm, and approximately 95% transmission from 1-6µm
