Roof mirror thorlabs.

Thorlabs offers hypotenuse coated right angle prism mirrors which are also known as turning mirrors. 97 5 reflectance in the 450 nm 2 µm range our selection of protected silver mirrors is well suited for use with femtosecond pulsed lasers. Thorlabs hollow roof prism mirrors are constructed using two uv fused silica right angle prism mirrors that have a protected aluminum uv enhanced aluminum protected silver ultrafast enhanced silver protected gold or unprotected gold reflective coating on their hypotenuses. Thorlabs expresses lidt for cw lasers as a linear power density measured in w cm.

In this regime the lidt given as a linear power density can be applied to any beam diameter. Thorlabs dichroic mirrors beamsplitters spectrally separate light by transmitting and reflecting light as a function of wavelength. Each mirror s hypotenuse is coated with either a broadband dielectric metallic or laser line coating. Thorlabs roof prism is made from n bk7 an rohs compliant version of bk7 and can be used when a right angle deflection of an image or laser beam is required.

One does not need to compute an adjusted lidt to adjust for changes in spot size as demonstrated by the graph to the right. Uv enhanced aluminum protected aluminum protected silver or protected gold. In passing through the prism the image is both deflected right to left and top to bottom.

Thorlabs offers right angle prism mirrors with the following reflective metallic coatings deposited on the prism s hypotenuse. A variety of sizes are available as well as prisms that come pre mounted in a 16 mm cage ø1 2 lens tube or 30 mm cage ø1 lens tube compatible housing.
