custom diameter optical lens

Custom Laser Quartz Objective Optical Welding Machine Rod Lens The structural integrity of a Custom Laser Quartz Objective is paramount for operational safety and precision. Our Rod Lens components are meticulously polished on both the cylindrical and flat end-faces to ensure a pristine Optic path. For an Optical Welding Machine, the choice of Laser Quartz is deliberate; its low coefficient of thermal expansion prevents "focus drift," a common issue where heat causes the

Focal Length Concave Glass Nova Display Fiber Uncoated Plano-concave Lenses Custom Meniscus Lens The Focal Length Concave Glass Nova Display Fiber Uncoated Plano-concave Lenses Custom Meniscus Lens is a precision optical component engineered for high-performance light control in display, fiber optic, and imaging systems. Designed with careful consideration of focal length and curvature, this lens family includes plano-concave and meniscus geometries to diverge or collimate

Custom Optical Glass Large Thorlabs Cylindric Aspheric Lens Factory Aspheric lens surfaces are used to correct spherical aberration (where the converging light from a lens does not have a common focal point, resulting in a distorted image) in lasers and imaging. Traditional spherical lenses cannot collimate light effectively because even small angles of incidence can produce spherical aberrations. This can mean that several components may be required to get the desired result

Optical Glass Half Rod Cylinder Lenses Cylindrical Lens A cylindrical lens with convex surfaces and square volume can turn a transmitted plane wave into a cylincrical wave, or turn an original cylindrical wave into a plane wave or spherical wave, such a kind of lens can correct ocular astigmation.
