The Plano-Concave Lens have one flat surface and one concave surface. They have a negative focal length and are used to diverge incoming light, or to

Optical grade Silicon is normally specified with a resistivity of 10 to 40 Ohm-cm which is higher than most semiconductor applications. The usual Sili

Optical domes are lenses with two concentric spherical surfaces. Sometimes they are being referred to as bent plan parallel plates. Consequently it is

These are lenses with one flat surface and one convex surface. They have a positive focal length and are used to converge or focus incoming light. The

Bi-convex lenses have a positive focal length. When the object and image distance are equal (1:1 magnification), not only is spherical aberration mini

Bi-concave lenses have two inward curved surfaces. These lenses have a negative focal length. Bi-Concave lenses are the best choice where object and i

Uncoated Sapphire windows are ideal for harsh conditions, including environments subject to high temperatures, high pressures, strong vacuum, or corro
