A narrow bandpass filter is an electronic or optical device that allows signals within a very specific frequency or wavelength range to pass through, while blocking signals outside of that range. Compared to standard bandpass filters, narrow bandpass filters are designed with a much tighter passband, often only a few nanometers in optics or a few kilohertz in radio frequency applications.

For many other bandpass filters, multi-band filters, and thick optical coatings, the coating designer must split the coating between the two surfaces to mitigate the effects of coating stress. In these cases, the second side coating is always designed to have a high transmittance and low reflectance region corresponding to the specified transmission band

When it comes to choosing the right optical lenses, you may find yourself debating between spherical and aspherical lenses.

A double concave lens—also known as a biconcave lens—is a type of optical lens that is thinner at the center than at the edges and curves inward on both surfaces. It’s designed to diverge light rays, meaning it causes parallel rays of light to spread apart after passing through.
An optical bandpass filter is a specialized optical filter that transmits light within a specific wavelength range while blocking light outside of this range. This range is often referred to as the passband, and it typically allows light with wavelengths within this band to pass with minimal attenuation, while light outside this range (both shorter and longer wavelengths) is significantly blocked.
When it comes to optical filters, choosing the right one can significantly impact the quality and effectiveness of your application. Longpass and shortpass filters are two common types, each with distinct characteristics and applications. In this post, we’ll explore the differences between longpass and shortpass filters to help you make an informed decision for your specific needs.
