AR Coatings

These coatings reduce the reflection from the surface of an optic. They are used to increase the throughput of the optical system and to reduce ‘ghosting’ and parasitic back reflections in an optical system.

Image
Beamsplitters

Beamsplitters selectively reflect a percentage of light and transmit a percentage of light.

Image
Bandpass Filters

A filter that has high transmission in one spectral region and low transmission at longer and shorter wavelengths. Bandpass filters are commonly used to trim the output of a light source or the input of a detector.

Image
CCD Filters

These filters are designed to improve the performance of CCD (charge-coupled device) chips. They act to trim the input to a CCD chip, reducing noise in a system.

Image
Coatings on Plastic

DSI offers extremely durable, non-absorbing, and complex thin film coatings on plastics. Single band, multi-band, and wide band multi-layer, anti-reflection coatings on engineered plastics are utilized in medical optics, UAV sensor suites, telecom, CPV solar systems, and more.

Image
Dark Mirrors

A dark mirror is a low reflective, low transmissive filter. Dark mirrors are used as the base for DSI Spectral Metal.

Image
Dichroic Filters

Dichroic, meaning two color, filters reflect certain wavelengths of light and transmit other wavelengths of light. These filters can be manufactured to reflect short wavelengths of light and transmit the longer wavelengths or transmit the shorter wavelengths and reflect the longer wavelengths.

DSI® Sunshade Thermal Space Material

A thermally insulating, broadband electromagnetic transmitting shield for satellite systems.

Image
Dual Band Filters

DSI’s precision dual bandpass filter technology brings new levels of performance with higher transmissions, steeper slopes, and flatter pass bands than traditionally found in the marketplace.

Image
Dual Mode Filters

DSI’s precision dual mode filter technology brings new levels of performance with higher transmissions, steeper slopes, and flatter pass bands than traditionally found in the marketplace.

Image
Edge Filters

These are dichroic filters with specific requirements for the placement and slope of the band edge.

Image
ITO FIlters

A family of indium tin oxide (ITO) coatings that transmit wavelengths of light and are electrically conductive. IM ITO (index-matched ITO) coatings are matched into the exit medium to yield higher transmission. Common applications are electro-static discharge and window heaters.

Image
Fiber Tip Coatings

Coating your fiber tips will greatly improve the transmission of your system. DSI’s proprietary coating process will uniformly coat your fiber tips for any wavelength that you require all while protecting your cladding from damaging heat.

Image Image
Heatbuster® Cold Mirrors

A cold mirror reflects short wavelengths and transmits longer wavelengths. It functions as a mirror to the ‘cold’ or short wavelengths.

Image Image
Heatbuster® Hot Mirrors

A hot mirror reflects long wavelengths and transmits shorter wavelengths. It functions as a mirror to the ‘heat’ or long wavelengths.

Image
Mirrors

A reflective optical device.

Image
MWIR Filters

MWIR bandpass filters with standard or self-blocking filter design for spectral sensing and imaging combine wide blocking and high passband transmittance in a single interference coating. They feature extreme stability in terrestrial and space environments.

Image
ND Filters

A coating that has a relatively flat absorption curve throughout a section of the spectrum.

Image
NIR Filters

NIR bandpass filters with standard or self-blocking filter design for spectral sensing and imaging combine wide blocking and high passband transmittance in a single interference coating. They feature extreme stability in terrestrial and space environments.

Image
Notch Filters

A coating that has high reflection in a narrow portion of the spectrum and high transmission at shorter and longer wavelengths. A common application is laser eye protection.

Image Image
Spectral Metal Coatings

The DSI trade name for a family of coatings on metal that selectively reflect and absorb light. Spectral Metal can be cut and formed after coating, allowing the system designer to use complex concave shapes within a low cost system. Spectral Metal is used in the UV printing and curing industry, medical imaging and LED systems.

Image
SWIR Filters

SWIR bandpass filters with standard or self-blocking filter design for spectral sensing and imaging combine wide blocking and high passband transmittance in a single interference coating. They feature extreme stability in terrestrial and space environments.

Image
UV Blocking

These filters block the ultraviolet (UV) and transmit the visible spectrum. These filters are used to prevent UV adhesives from curing prematurely, to slow spoilage in fresh produce, and to protect fine artwork.

Image
Visible Filters

These are filters that operate in the visible spectrum between 400 nm and 780 nm.
