A bessel lens consists of axicon lenses and two sets of focusing lenses. The collimated light passes through the axicon lens to form the bessel beam.
Category: Application Notes
Precision laser applications require fine power control. A variable beam splitter with a large dynamic range and precision control is designed to fulfill this purpose.
When high-voltage equipment discharges electricity, arc discharge may occur depending on the electric field strength, during which electrons in the air continuously gain & release energy, emitting UV rays.
Short-wave infrared (SWIR) light is a second of the electromagnetic spectrum typically in the 0.9μm to 2.5μm range and is therefore invisible to the human eye.
One of the technology engines in high value-add photonics service is in the area of high-power lasers and applications, ranging from scientific to precision material processing.
Chalcogenide material is gradually taking over Germanium in the broad IR regime. It performs especially well within the 8 to 12μm range due to its lowest absorption and dispersion in LWIR.
Micro-lenses are sub-micrometer lenses (often up to 10 microns), typically made with fused silica due to its excellent transmission characteristics of UV to IR rays.
Mid-IR regime is proven to have rich absorption “finger-prints” of materials, demonstrated by benchtop measurement tools, such as Fourier Transform Infrared Spectrometer.
Image processing capability integrated together, with optical/mechanical/electronics capabilities, can deliver system-level solutions for the manufacturing industry.
Mid-IR borescope is an imaging instrument with customizable requirements for clear inspection of hard-to-access areas, such as boiler tubes, furnace walls, etc.
