Fiber Optic Tunable Filter
The Fiber Optic Tunable Filter is based on fiber Fabry-Perot interferometer technology. Activated by a piezoelectric transducer, the device can be tuned across the entire C + L band. It is ideal for applications in signal selection, noise rejection, and spectrum analysis. Two thermistors are mounted in the filter package for temperature monitoring.

Laser Interferometric Length Measurement System YJGCC1000 Interferometers Ccyj-optics
Laser Frequency Stabilization Accuracy: ±0.02ppm Measurement Range: 1mm-4000mm Dynamic Acquisition Frequency: >100kHz
The laser interferometric length measurement system calibrates gauge blocks, measuring rods, scales and coordinate measuring machines in temperature-controlled, humidity-controlled and vibration-isolated metrology rooms. It supports precision measurement over large ranges of tens of meters and measurement of very small motions such as watch components. It measures geometric quantities including length, angle, straightness, parallelism, flatness and perpendicularity, and supports specialized applications such as micropositioning in semiconductor lithography and measurement of recording-track spacing in computer storage. The system retains high stability, accuracy and sampling rate while integrating the light source and measurement-signal reception and processing into the main unit, providing a more convenient, user-friendly integrated design.

Founded in Beijing in 2011, Beijing FJR Opto-electronic Technology Co., Ltd. specializes in R&D, manufacturing and sales of infrared thermal imaging equipment and complete optoelectronic systems.
A microlens array (MLA) is a high-precision optical component composed of hundreds or thousands of tiny, uniformly arranged micro lenses on a single flat substrate. Unlike traditional single lenses that focus one light beam, a microlens array can split, homogenize, and reshape light on a micro scale. It is widely paired with VCSELs, lasers, and image sensors, becoming a core part of modern miniature optical systems.
A laser bar is an array semiconductor laser chip integrated with dozens of emitters, which realizes hundred-watt quasi-continuous output on a single chip. With regular emitter arrangement and controllable fill factor, integrated thermal design and superior wall-plug efficiency compared to single chips, it acts as the core light source for high-power pumping, medical lasers and precision processing.
