    Neutral density wire mesh filter, transmitting a percentage of incident light, mounted in an FT style holder. These filters are robust to high-powered applications (such as solar simulation), do not affect the non-uniformity of the target, and transmission is spectrally flat. Please select the desired transmission percentage for your application.

    Each filter is mounted in an FT-style filter holder (compatible with most Sciencetech solar simulators and FB-style filter boxes).
    Each filter is 76 mm in diameter (3").

    This standard optical liquid filter is equipped with fused quartz windows (270 to 2500 nm) which transmit UV light and can be used for UV applications. It can be operated either horizontally or vertically but horizontal operation is preferable due to potential risk of air gap in the light path. Aluminum provides superior heat transfer compared to stainless steel but should not be used in corrosive environments.

    An AM1.5D 3x3" air mass filter (including filter holder) designed for Sciencetech's:
    -Flash Series Solar Simulators (Class A, ASTM E927-19)

    AM1.5D simulates the terrestrial solar spectrum on the ground when the sun is at a zenith angle of 48.2°. It includes only direct light from the sun, and not the diffuse light that is scattered by the atmosphere. As a result, this filter simulates the direct radiation which reaches the ground.

    Four filter sort order filter set covers a spectral 200-1600nm range (UV-NIR).
    Order sorting filters are used with diffractive equipment such as monochromators to filter out harmonic diffractive orders.
    This absorbing glass sort order filter set provides modest harmonic blocking for spectroscopy systems.

    Filters are 1" diameter

    Note: absorbing glass type filters may exhibit flourescence. These filters cannot be used with high power light sources
