Micro-Patterned Optical Filters

Combining patented microlithography expertise with state-of-the-art coating technology to enable smaller and simpler optical designs for portable or complex optical systems.

Custom Optical Coatings

Precision optical coating – with decades of thin film engineering experience and a portfolio of advanced optical coating platforms to match your performance, throughput and cost requirements.


PixelSensor™ multispectral sensors use exclusive on-chip filtering to pack up to 8 wavelength selective photodiodes into a compact 9 x 9 mm array format for simpler and smaller optical devices.


Multispectral wheel cameras offer a sophisticated, flexible platform for development and deployment of various imaging applications. Available in UV, VIS, and SWIR versions.


Multispectral cameras provide live imaging of 3-9 spectral bands at video rates. Custom dichroic filter arrays are integrated into the focal plane array at wafer-level to create robust linear and area sensors that extract high-contrast spectral information at specific visible and infrared wavelengths.

Optical Measurement & Reference Devices

Specular reflectance standards can be used as a reference when measuring surfaces with thin film coatings, anti-reflective coatings, blocking filters, optical substrates, optical coatings, machined metals, and semiconductor materials.

Shear-Plate Collimation Testers

Usable in the 350-2500nm wavelength range, each CT consists of a wedged, high-quality optical flat that can be used to examine and adjust the collimation of laser light or to measure wave-front curvature and quantify divergence/convergence magnitude.

Optical Flats | Fused Silica

Finely polished flat surface used as a reference against which the flatness of a test surface may be compared. We offer single-sided optical flats in either fused silica or Zerodur®. The flats can be enhanced with an aluminum coating to increase contrast and improve the visual reference.

Linear Variable Filters

One specialty of Salvo Coatings is Linear Variable Filters scalable with volume and is a compact solution for many of today’s optical challenges. By compressing the optical train, LVF’s allow users to make spectroscopic devices with a monolithic element (Sensor plus Filter).
