Frameless Unit
Frameless mounting is designed to minimize product footprint and maximize the front surface area of the mirror used.
Our Frameless beamsplitter unit are produced using a synthetic fused silica with low thermal expansion ratio equivalent to Zerodur® to provide manimum thermal stabikity.
