기능

• By making both sides convex, this lens can efficiently refract light in a small space and collect more light.
• Use this function when you want to collect collimated light at the shortest distance possible or when you want to collect as much light as possible from the emission point.
• It is a lens made of synthetic quartz with high laser resistance that can be used in ultraviolet light below 350 nm.
• It can be selected according to your specifications from the wide variety of subdivided by outer diameter size and focal length.
• Chromatic aberration corrected achromatic lenses (DLB) are also available.
• * Spherical biconvex lenses have chromatic aberration, and the focal length depends on the wavelength.
• * The spherical aberration of a biconvex lens is larger than that of a plano-convex lens, and the focus spot may not be concentrated at one point.
• * The transmittance of the uncoated product is about 90% due to the loss caused by the reflection of the front and back of the lens.
