Light transmission is important when it comes to optical filters, but effective blocking levels and ranges should be utilized as well to ensure optimal performance. Effective blocking levels and ranges are essential in preventing unwanted wavelengths from passing through the filter, which could interfere with the desired signal or image. Let’s look closer at these two essential filter characteristics: Blocking Level: A measure of the out-of-band attenuation of an optical filter over an extended range of the spectrum. The attenuation level is often defined in units of optical density. Blocking ..read more

What are smooth shape laser beams? Smooth shape laser beams are characterized by uniform intensity of illumination across the beam profile or focused laser spot. Such beams do not have large changes in uniformity, and often have a flat-top-like intensity envelope. Most laser sources do not have a smooth shape laser beam profile, but rather either a Gaussian profile (for single mode lasers) or a complex centroid profile (for multimode lasers). Getting smooth shape laser beams from multi-mode lasers High laser power can be more easily and affordably achieved using multi-mode lasers, compared to ..read more
