Multi-Edge Filters

Multi-Edge Filters

At Optical Filter Shop, we carry high-performance, multi-edge filters that are ideal for fluorescence microscopy, high-speed imaging and numerous other applications. These filters have regions of high transmission and reflection separated by a steep edge.

We can customize our multi-edge filters to your specific needs to ensure the best performance.

Our Multi-Edge Optical Filter Options

We offer two types of multi-edge filters:

UV-IR Filters

PIXELTEQ UV-IR filters block ultraviolet (UV) light and infrared radiation (IR) from high-intensity arc lamps in projection display systems. They suppress light that can damage polymer optics, microdisplay panels and other optical components. They also reduce the heat load on these components throughout the optical train.

These filters benefit from a proprietary sputter deposition technology, which creates a dense coating with exceptional optical stability in varying environmental conditions and high operating temperatures.

Other features and benefits of our multi-edge, UV-IR filters include:

• Excellent color integrity with no color shift.
• Narrow cut-on/cut-off edge tolerances.
• High visible transmission.

Dichroic Color Filters

PIXELTEQ dichroic color filters provide consistent, vibrant color for many detection and illumination applications. Also known as interference or thin-film filters, these color filters have a multilayered sputtered coating for durable, shift-free performance. They also resist aging and fading in high-output luminaries.

Additional features and benefits of these multi-edge color filters include:

• Rich saturated colors.
• High transmission with low absorption.
• Spectral stability indoors and outdoors.
• Standard and custom color availability.

Multi-Edge Filter Applications

These multi-edge optical filters can be used for a range of applications, including:

• High-intensity lamps.
• Lighting reflectors.
• Projection displays.
• Original equipment manufacturer (OEM) optical systems.
• OEM sensing and imaging.
• Broadband illumination and light engines.
• Technical, architectural and entertainment lighting.
• Copy and print processing.
• Machine vision.

Integrated Options

Multi-edge UV-IR and color filters are often combined or matched with each other or different filter types to provide the best performance for your application. Some complementary filter types include:

• Cold mirrors: Cold mirrors transmit infrared light and heat while reflecting visible light into the illumination path.
• Color correction filters: Color correction filters alter the correlated color temperature of one lamp to match another.

Custom Multi-Edge Optical Filters

At Optical Filter Shop, we offer custom UV-IR and color multi-edge filters. We engineer our filter solutions to your specific optics and illumination source to deliver your targeted color output. We also match specific wavelength, angle, size, substrate and shape requirements.

For color filters, we can pattern on flags or gradient wheels to provide smooth CMY or RGB color mixing. We can also micro-pattern multiple colors to create full-color and photorealistic imaging effects and gobos.
