Often thought of as “IR-cut” filters, Shortpass Filters are specifically designed to pass a broad spectrum of shorter wavelength light, while blocking longer visible (VIS) and near-infrared (NIR) wavelengths. - Designed to have a sharp transition between shorter wavelengths (which are passed) and longer wavelengths (which are blocked) - Peak transmission ?90%* - Can be used with Longpass Filters for a custom, fine-tuned Bandpass Filter - Anti-reflection coated for maximum transmission - Exceptional surface quality; 40/20 scratch/dig - Available in wavelength ranges from 340nm to 785nm *Peak Transmission SP701 = 85%, SP705 = 88% Shortpass Filters are commonly used in color imaging to achieve natural color rendering. They can also be used to protect the sensor from NIR laser damage or to reduce IR radiation or “camera bloom” created during hot metal or glass extrusion processes.

MidOpt Neutral Density Filters serves as “sunglasses” for your system and can be used with monochrome or colour cameras. Designed to reduce light intensity neutrally over a specific wavelength range without affecting image colour or contrast. - Available in a variety of optical densities - Reduce light intensity while maintaining a wide aperture and shallow depth of field. Every 0.3 density increment equals one f-stop - Minimize pixel saturation - Can be stacked with other Neutral Density Filters to test various optical densities - Exceptional surface quality; 40/20 scratch/dig Applications include imaging in intense lighting situations (i.e. molten metal and welding), outdoor aerial imaging and photography. Neutral Density Filters help reduce shutter speed to create blur, preventing a “jello” effect in aerial imaging. For more information, please feel free to consult the datasheet below.

Polarizers are designed to reduce specular glare by passing only the light polarized in the direction perpendicular to the reflected light (glare). In addition, they help improve contrast, increase colour saturation and detect imperfections in transparent materials. MidOpt Polarizing Filters can be easily and securely mounted to your lens and light source for maximum extinction or glare reduction. - Contrast ratios average up to 10,000:1 - Linear, circular and wire grid polarizers are available for visible (VIS) and near-infrared (NIR) spectrums - Rotating mount with locking thumb screw to fine tune glare reduction - Exceptional surface quality; 40/20 scratch/dig Polarizers are commonly used to reduce glare from non-metallic in objects with smooth surfaces or surfaces covered with grease, oil or liquid. For best results, use an optical-grade Polarizer over the lens and Polarizing Film over the light source. The PR120/PG120 offers ultra-high contrast and an anti-reflection oleophobic coating.

Acrylic Longpass Filters are a durable, lightweight and economical solution for inspection windows. They can protect a lens in environments where broken glass might pose a problem. - High transmission ranging from 90 to 98% - Available with an anti-reflection coating for maximum transmission - Optical-grade acrylic - Impact-resistant - Half the weight of glass Acrylic Longpass Filters are frequently used for lens protection and economical enclosure windows, as well as over light sources to control the wavelength emission of broad spectrum light sources. Because of their durability, they’re commonly used in Food & Drug Administration (FDA) and European Food Safety Authority (EFSA) regulated applications where glass over the inspection area is not permitted. AC370 and AC380 offer anti-abrasion, anti-reflection coating, which can also withstand harsh solvents such as alcohol, acetone or MEK.
