BBO (a -BaB 2 O 4) is a negative crystal at high temperatures. It exhibits high birefringence over a wide transparent range of 189 nm to 3500 nm. The physical, chemical, thermal, and optical properties of the a-BBO crystal are comparable to those of the b-BBO crystal. However, due to the centric symmetry of its […]
Or focusing applications utilizing monochromatic illumination, in a range of industries including industrial, pharmaceutical, robotics, or defense. Plano-convex Lenses have one convex surface. For maximum efficiency, the second, Plano (flat) surface should face the desired focal plane. Plano-Convex lenses are commonly used in a wide range of applications or industries. Astar photonics are points are […]
Plano-Convex lenses are the best choice for focusing parallel rays of light to a single point. They can be used to focus, collect and climate light. The asymmetry of these lenses minimizes spherical aberration in situations where the object and image are located at unequal distances from the lens. N-BK7 lenses are a great choice […]
LBO crystal is grown with an improved flux method. LBO is an orthorhombic crystal and belongs tothe point group mm2. It is built up of a continuous network of B3O7 groups, with lithium cations locating in the interstices. Thecompact network of B3O7 groups makes the LBO crystal almost free of inclusion. Now, A-STAR provides high-quality […]
Plano-concave lenses are useful for a wide range of applications. These lenses are manufactured from BK7A grade A (or customer design) optical glass and are supplied uncoated. Anti-reflection coatings are available as listed earlier in this section. To order an anti-reflection coated lens, simply append the wavelength in nanometers to the product number. A-STAR photonics […]
