Custom Size Optical Circular Glass Lens for Industrial Sensors and Optical Instruments
Material
The lenses are precision-manufactured from optical-grade glass, typically borosilicate (BK7) or other specialized formulations like fused silica. The material selection depends on the specific application requirements for refractive index, transmission properties, and environmental stability.
Key Properties
Custom Dimensional Specifications: The primary characteristic is the availability in non-standard diameters and thicknesses, tailored to fit unique housing designs and optical path requirements.
High Surface Accuracy: These lenses feature precisely controlled surface quality with tight tolerances on curvature, parallelism, and centration to ensure optimal optical performance.
Excellent Transmission Characteristics: They provide high light transmission across specified wavelength ranges, from UV to IR, depending on the glass type selected.
Thermal and Chemical Stability: The lenses maintain dimensional stability and optical properties under temperature variations and exposure to various industrial environments.
Primary Function
These circular lenses serve multiple optical functions including light collection, focusing, collimation, and imaging. They act as protective windows, objective lenses, or beam shaping elements in sophisticated optical systems, ensuring precise light management according to the instrument's requirements.
Applications
These custom components are essential across numerous technical fields where standard optics cannot be utilized:
Industrial Sensors - for barcode readers, proximity sensors, and optical encoders
Measurement Instruments - in laser rangefinders, spectrophotometers, and analytical equipment
Medical Devices - for diagnostic equipment, endoscopic systems, and laboratory instruments
Defense and Aerospace Systems - in targeting systems, surveillance equipment, and navigational instruments
Research and Scientific Equipment - for microscopes, telescopes, and experimental optical setups
In summary, custom size optical circular glass lenses represent a critical solution for engineers and designers developing specialized industrial sensors and optical instruments where precise dimensional requirements must be met without compromising optical performance.
