Spectralon Reflectors

NORTH SUTTON, N.H., July 27, 2007 -- Labsphere Inc. said its new Spectralon laser-pump reflectors, the efficiency of which lamp- and diode-pumped lasers and dye lasers rely on for optimum performance, combine maximum reflectance with the flexibility that comes from machine fabrication.

This efficiency, coupled with economical machined part flexibility, is an ideal choice for laser OEMs.

Spectralon’s reflectance rate and near-Lambertian diffuseness deliver more watts per square meter with greater beam stability and uniformity. This more predictable beam profile has reduced susceptibility to parasitic oscillations compared to metal, ceramic, or powder-based reflectors. Spectralon’s long-term optical stability ensures consistent and reliable laser performance over time, Labsphere said.

Unlike expensive and intricate molded reflectors, these machined laser-pump reflectors can be economically fabricated into a wide variety of shapes to meet any reflector design. In-house machining allows samples to be created quickly and easily, and modified throughout the design, prototyping and testing process. This manufacturing flexibility means low or high volume quantities can be ordered without affecting price, according to the company.

Labsphere said its engineering staff has an established industry-wide reputation for its knowledge and experience in laser cavity design, and often collaborates with customers to develop custom laser-pump reflector designs.

Obeying Lambert's cosine law.
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
The ratio of reflected flux to incident flux. Unless otherwise specified, the total reflectance is meant; it is sometimes convenient to divide this into the sum of the specular and the diffuse reflectance.
