Red Description

At Optical Filter Shop, we feature an entire line of dichroic color filters that change the basic appearance of light. Our red color filters transmit the longer visible color wavelengths while reflecting the shorter wavelengths. We use a sputtering process to apply multi-layered coatings that provide stable and durable performance under the most demanding light settings.

While many traditional color filters consist of polymer gels or absorptive colored glass, our red dichroic filters are absorption-free, using thin-film interference technology to produce the most superior transmission of rich red colors. We craft our dichroic filters with a steep edge transition between the shorter and longer wavelength transmission bands to provide accurate measurements and the most effective reflective properties.

Measurement and Other Applications

Our red color filters are ideal for measuring specific luminary properties using a spectrometer or other sensing devices. Among the most common applications of red dichroic filters are:

  • Spectral radiometry.
  • Machine vision algorithms.
  • Color separation in cameras.
  • Cinema and projection.
  • Graphic arts.
  • Entertainment and concert venues.

Red Optical Filter Options

Optical Filter Shop’s red color filters come in 18 different stock options that accurately measure wavelengths in both the long wave pass (LWP) and short wave pass (SWP) regions. Several advantages and benefits include:

  • Durable coating construction for high output light sources.
  • Lifetime performance without aging or fading.
  • Low absorption and high transmission properties.
  • Superior performance indoors and outdoors.
  • Fully customizable.

Our red stock filters are also perfect for sampling and prototyping. Rather than committing to a large-volume custom run, purchasing a single stock filter can provide significant cost savings. If we have the filters you need in stock, we can usually ship in as little as 24 hours.

Purchase Custom Red Optical Filters

Many of our stock filters are customizable to meet the needs of your application and industry. The customization process is often as easy as letting us know the filter’s style, shape and size. We can also pair multiple filters together in the same application to provide even more versatile features.

Specific designs that work well with red filters include:

  • Color correction filters: These filters can adjust the light temperature, white balance and overall light beam color.
  • UV filters: Ultraviolet (UV) filters block out harmful UV light while transmitting the desired color.
  • Cold mirrors: Cold mirrors block heat from the back of the filter to reflect more visible light.
  • Color gobos: A gobo is a stenciled or patterned fitting that can create a projected image or pattern.
  • Patterned color filters: These filters allow multiple colors to blend or pattern together to produce variations.

Should your filters require more enhanced customization, our engineers can design an option to achieve peak performance for your application. Our team has decades of experience with coating technology to help you find the right solution for your needs. Our top priority is increasing the performance and maximizing the efficiency of your operation.
