Linear Variable Filter (LVF)
Based on the provided image, the product is a circular Linear Variable Filter (LVF) wafer with a grid-segmented surface. The coating shows a continuous color gradient from green at the bottom, through yellow, to orange-red at the top, indicating that the spectral response (transmitted or reflected wavelength) varies continuously along one axis of the filter. The grid lines divide the wafer into regular segments, suggesting that the coated wafer can be diced into individual filter chips or used directly as a filter array aligned with detector pixels. The gold-colored edge indicates a coated optical substrate. This type of filter is commonly used to replace multiple discrete bandpass filters or gratings in compact spectral instruments. Note: the provided material contains only the product image without textual specifications, so the description is based on visible characteristics of the product.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
An infrared transmitter (IR transmitter) is a basic electronic component that sends invisible infrared light signals for short-range wireless control. It is widely used in daily electronics, smart home devices, and industrial equipment due to its low cost, low power consumption, and stable performance.
