Negative Filter
Notch filters,also called band-stop or bandwidth-rejection filters,transmit most wavelengths while strongly attenuating a selected stop band,typically10-60nm wide. They are the inverse of bandpass filters:bandpass transmits inside and rejects outside,whereas notch filters reject inside and transmit outside. Typical in-band blocking is OD5-OD6. They are useful for rejecting laser emission; in Raman spectroscopy,pump-laser suppression improves signal-to-noise ratio by placing a notch filter in the detection path. Other applications include laser fluorescence instruments and biomedical laser 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.
