Reliable Performance with Multiple Wavelength Selectivity

JDSU manufactures a wide range of optical assemblies, including:

• Prism assemblies
• Color wheels
• Fixed and linear variable filter assemblies

For applications that require multiple wavelength discrimination coupled with small detectors, edge-bonded assemblies are often the most cost-effective solution.

Edge-bonded assemblies typically have three to five separate filter elements cemented edge-to-edge to form a single substrate.With suitable mounting hardware, the edge-bonded assembly is typically mounted in close proximity to the detector. This eliminates the need for large filter elements near the entrance to the optics system.

Each filter element of the assembly is cut from an oversize, coated module, which results in a wide range of possible sizes and materials for the final assembly.

Edge-bonded assemblies are ideal for many applications where space, weight and survivability are the most important considerations.

We offer other products for spectroscopic applications. Our complete production facilities can support your optical filter requirements from prototypes through OEM volumes.We provide worldwide customer service and technical support.
