Optics & Optical Coatings

There is a large choice of filters, their characteristics are thoroughly differentiated.
To choose the right filter characteristic may help you to increase your experimentation efficiency.

ND Filters

The transmittance can be fine tuned and offer the possibility of light intensity adjustment.
The metal coating reflection provide an extremly smooth transmission wavelength characteristic from the UV to the IR wavelength.

Filter Case


A plate directly fixes the collimating lens to the 30mm cage system. A375T / A355T (M9x0.5) and other standard screws are also supported.
It is a holder for incorporating optical elements such as lenses and filters into the cage system.
Higher moment of inertia to maximize stiffness and faster to reach thermal equilibrium characteristics are achieved by a hollow-frame design....
