Description

This is our newest “must have” item. This device increases safety and reduces the risk of laser damage by trapping the beam entered into the aperture.

Our laser beam dumps fit for most beam sizes and can be used in a lab or any other optical system.

It is suitable for CW and pulsed beams up to 20W/cm2 (tested value).

Wide wavelength range: from EUV through VIS and up to LWIR.

The built-in mounting suits a standard optical stand (M6 x 1.0) and can be easily held. In addition to the unique design the advantage of having Acktar’s coatings implemented into the device you get the reflectivity factor of less than 10-6.

Acktar’s anti reflective coatings have been tested under a various conditions and the results presented show that Acktar Black Coatings exhibit very impressive Laser Induced Damage Threshold values under a broad variety of conditions and constitute an excellent choice where a combination of high absorptance and high tolerance of laser energy is required.
