Plastic Laser Filter WindowsCost-effective, lightweight protection in large sizes for low power lasers and diffuse reflections from high power lasers
We have three ranges of plastic laser filter windows, the TT- range, LV- range and GL- range. Details are shown in the tables below. Please note that we are able to supply any of these filters in custom sizes up to the largest size available (typically 915 x 610 mm). We are also able to supply them machined to an engineering drawing if desired, ready for assembly into your system. This may well be cost effective for larger numbers of windows or where there is an ongoing requirement.
In the TT- range OD curves can be seen by clicking on the filter reference.
