Notch

Notch Optical Filters

Notch optical filters are an ideal choice for numerous illumination and detection applications. They block a preselected wavelength region while transmitting all other wavelengths outside that blocked region. They can also be used to remove a single laser wavelength from an optical system.

At Optical Filter Shop, we provide custom notch filters designed to your precise specifications.

Notch Filter Features and Benefits

Our PIXELTEQ notch filters deliver rich, saturated colors with exceptional stability in virtually any environment. They provide durable, shift-free performance and reliable support for high-output lamps.

Unlike absorption filters or polymer gels, these filters are practically absorption-free. You’ll get superior transmission, striking colors and lifetime performance with no fading or aging.

These filters also have steep edge transitions between longer and shorter wavelength transmission and reflection bands — significantly steeper than polymer gels or colored glass.

Notch Filter Applications

Notch filters have many practical applications, including:

• Entertainment, architectural and technical lighting.
• Original equipment manufacturer (OEM) sensing and imaging.
• Copy and print processing.
• Machine vision.
• Digital projection and cinema.

Complementary Filter Options

You can match or combine your notch filter with other filter types to optimize its performance in your specific application. Complementary filter options include:

• Patterned color filters: These filters provide smooth mixing from zero to full color saturation. You can also use them to mix wide and rich color gamuts.
• Color gobos: Full-color and multicolor gobos are micro-patterned for high-resolution, photorealistic images and effects.
• UV-IR filters: These filters transmit visible color and block damaging ultraviolet (UV) and infrared light.
• Cold mirrors: Cold mirrors transmit infrared heat and light outside the device and reflect visible light into the illumination path.
• Color correction filters: These filters match the correlated color temperature of one lamp to another.

Our Customization Options for Notch Filters

At Optical Filter Shop, we’re dedicated to meeting all your requirements. We create filters tailored to your specific illumination source and optics to achieve your desired color output. We also match your cut-on and cut-off wavelengths and calibrated colors.

We can pattern your notch color filters on gradient wheels or flags for superior RGB and CMY color mixing. Additionally, we can micro-pattern multiple colors using gobos and other photorealistic imaging effects.

If you need a specific size, shape or substrate, we can accommodate those requirements to ensure the optics fit your application.
