Biconvex Lenses for Optical Systems

Knight Optical can offer Custom Homogenizing Rods for use within Electrical Instruments. Electrical instruments use backlight displays to help illuminate and evenly distribute the light source. They can be used as mixers, which is when you want to mix colours from multi-colour LEDs together. The light source will enter a light pipe at a variety of incident angles, which is designed to utilise its total internal reflection to help transmit light from the entrance of the light pipe to the exit. The material’s refractive index is the only factor which affects the light pipe’s critical angle; this defines the angle of acceptance at which the total internal reflection will occur.

Knight Optical can offer custom Rod Lenses for use within Optical Systems. We supply a range of custom & stock Rod lenses for a range of applications. All individually QA checked and metrology tested for quality to ensure parts meet customer specification. Supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications. Knight Optical supply precision optical components to customers with Optical systems. Rod Lenses are a special variant of cylindrical lenses so they focus light to a line. Rod lenses have an outside face that is polished and the ends are ground. Typical uses for rod lenses would be to generate a line image from a circular laser beam. Rod lenses can be cut at 45 degrees for use in beam steering and other similar applications.

Knight Optical can offer Planoconvex Lenses for use within Optical Systems. We supply a range of Planoconvex lenses for a range of applications. All individually QA checked and metrology tested for quality to ensure parts meet customer specification. Supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications. Knight Optical supply precision optical components to customers with Optical systems. Planoconvex lenses are simple lenses with a plane surface and a convex surface and form a moderate quality image close to the axis. They are generally used as elements within a more complex lens system or optical instrument in imaging systems, collimation, lasers and detectors. For more information read the PDF…

Knight Optical can offer Planoconcave Lenses for use within Optical Systems. We supply a range of Planoconcave lenses for a range of applications. All individually QA checked and metrology tested for quality to ensure parts meet customer specification. Supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications. Knight Optical supply precision optical components to customers with Optical systems. Planoconcave lenses are simple lenses with a plane surface and a concave surface and form a moderate quality image close to the axis. Concave lenses have a broad range of applications including, focussing and control of laser beams, moderate quality imaging and other optical instruments. In a multi-element optical system they reduce the power of the system. Used on their own they form a diverging cone or virtual image. A typical use for concave lenses would be in a beam expander.
