Acktar Beam Traps and Beam Blocks

Acktar Blackened Laser Beam Traps and Blocks feature proprietary coatings designed to absorb incident laser light from the ultraviolet (UV) to the long-wave infrared (LWIR) spectrums. These Acktar coatings can achieve a reflectivity factor of less than 10-6 (beam trap designs) and have laser damage thresholds up to 20 W/cm 2..

Axicons, UV Fused Silica

2017/9/8A Bessel beam is a non-diffracting beam of concentric rings, each having the same power as the central ring. Technically, a Bessel beam cannot be created as it requires infinite energy. A beam closely resembling a Bessel distribution can be generated by passing a Gaussian beam through an axicon and taking the projection of the beam close to the axicon's conical surface.

PL15 Laser Beam Dump

The PL15 Laser Beam Dumps is used to absorb incident light and capture unwanted laser beams. In the optics laboratory, they are used to stop stray laser beams to protect personel and equipment. In instrumentation, laser beam dumps and traps are used to contain a beam within a portion of the instrument.The anti-reflective property of a laser beam dump can be characterized by the apparent

2021/4/21A single-mode circular beam profile from the SC4500 (top) is contrasted with the collimated beam generated from a thermal source, which is spatially incoherent (bottom). By carefully considering the tradeoffs of various methodologies and architectures, the key desirable features of high brightness, good beam quality, broad spectral coverage, and shot-to-shot stability can all be achieved.

Light Accessories

Thorlabs offers a variety of light accessories for labs. Available are laser safety accessories such as laser glasses, laser safety curtains, beam blocks, and shutters. For broadband, non-laser light, we offer blackout curtains, optical enclosures, and a variety of blackout materials.

Thorlabs

Thorlabs' selection of Beam Traps and Beam Blocks are common laser lab safety devices. They are designed to be the terminal piece of an optical system and absorb the incident laser beam. The beam traps that feature both 4-40 taps for integration into a 30 mm cage system and an 8-32 (M4) tap for post mounting are suitable for CW (BT600) or CW and pulsed (BT610 BT620) beams up to 80 W.

Dear Thorlabs, Your optical enclosure stuff is great but one thing that would make everything a LOT easier is if you were to sell your black hardboards at 24.5 x 24.5 instead of 24x24. Your standard longest rail is 24 inches, however you actually need a board 24.5 long to fit between a 24 inch rail since the board should fit inside the indentation of the rails.
