Laser Light Houses are glass components with polished faces that are highly parallel. They are used as a protective element between two environments and their impact on the passage of light is neutral.

The choice of material affects not only the useful transmission wavelength range, but also such factors as pressure handling capability and thermal conductivity.

These laser protection windows are used in laser levelling devices and other applications where protection from ambient influences are required (water, dust, etc.). The planed edges allow sealing with O-rings or gaskets for a watertight seal.

Our protective laser light houses are precision manufactured for an absolute minimum in unwanted beam deflection. Anti-reflection (AR) coatings are generally applied to both surfaces of each window to prevent back reflections, interference effects, ghost images, and light loss.

Laser safety windows are used in surveying instruments, e.g. leveling, theodolite, rotation lasers.

These items are not stocked and will be manufactured on customer request only. Please contact us with your detailed requirements.
