Zoom

Extremely thin beamsplitter. It can be inserted into an optical light path without any beam shift or chromatic dispersion for any light transmittance application.

◦We offer 2 choices of thickness, 300um and 90um.
◦Dielectric multi-layer optical coating with reflectance and transmittance ratios at 1:1.
◦Dielectric multi-layer optical coating on the front surface and AR coating on the rear surface to provide a mirror with no loss of power.
◦Due to the fabrication method, these offer good durability and high resistance against vibration making them an excellent alternative to traditional pellicle beamsplitters.

Attention

▶Thin beamsplitters are extremely thin and fragile. Special care must be taken during cleaning and handling.
▶When removing dust from the surface, do not use optics tissue paper to clean. Use a compress gas spray instead.
▶When applying a laser linear polarized light, the direction of polarization may affect the amount of reflectance and transmittance. For divergence usage of 1:1 ratio, ensure the direction of polarization is set to 45 degrees or use a circular polarizer.
▶The transmittance wavelength properties may be different if the incident angle is other than 45 degrees.
▶Avoid pushing the glass retainer as the mirror can bend or break. When handling, please use the other metal frame.
▶The surface reflectance accuracy may deteriorate when used outside recommended operating temperature.
▶The phase difference of incident light cannot be preserved on light transmittance and reflectance. Please use a wave plate to compensate.
