Double concave lens【Lenses】

The Double Concave Lenses are made from BK7 material, which are manufactured with both surfaces concave. These lenses have negative focal lengths. These lenses diverge collimated incident light and form virtual images, which are seen through the lens..

Plano concave lens【Lenses】

The Plano Concave Lenses are made from BK7 material, which are manufactured with one concave surface and one plane surface. These lenses have negative focal lengths. These lenses diverge collimated incident light. They form virtual images which are s..

Double convex lens【Lenses】

The Double Convex Lenses are made from BK7 material, which are manufactured with an identical convex surface on both sides of the lens. The Double Convex lenses have positive focal lengths and form both real and virtual images. We also provide

Plano convex lens【Lenses】

The Plano Convex Lenses are made from BK7 material. It presents a curved interface and a planar interface. They are for instance the microlenses situated on top of a wafer, but can also encountered in macroscopic optical systems. Their asymmetrical n..

Beamsplitter Cube【Prisms】

Cube beamsplitters are constructed by cementing two precision right angle prism together with appropriate interference coating on the hypotenuse surface. The absorption loss to the coating is minimal transmission and reflection approach 50% (averageC..

Corner Cube Retroreflector【Prisms】

Corner Cube Retroflectors are used to reflect light beam back to the direction that it comes from. The reflected beam is always parallel to the incident beam, and it travels in the reverse direction of the incident beam. This holds true regardless of..

Dove prism【Prisms】

Dove prism is a type of reflective prism which is used to invert an image. Dove prisms are shaped from a truncated right-angle prism. A beam of light entering one of the sloped faces of the prism undergoes total internal reflection from the inside of..

Penta prism【Prisms】

Penta Prism is a five-sided prism containing two reflecting surfaces at 45?to each other, and two refracting faces perpendicular to the entering and emerging beams. The deviation angle of 90deg is thus independent of the orientation of the prism, mak..

Right angle prism【Prisms】

Right-Angle Prism is used as a mirror to deviate light through 90 degree, and also as a retroreflector to deflect light through 180 degree by total internal reflection.Specifications: Material: BK7 Diameter Tolerance: +0.0/-0.2mm Angular Toler..

Rotator【Waveplates】

The plane of polarization of linearly polarized light will be rotated by quartz crystals due to the optical activity. The optical axis in a polarization rotator is perpendicular to the polished face. The orientation of input linearly polarized light ..

Low order waveplate【Waveplates】

Multiple Order waveplates(Low Order Waveplate) are made so that the relative phase change is larger than the required value by an integer multiple of 2. While the performance at the design wavelength can be essentially the same, chromatic dispersion ..
