SWIR Lens
1. Introduction of SWIR lensesLight is a kind of electromagnetic wave, with the visible spectral of 0.38-0.76um, and the infrared spectral region of 0.76-1000um.The part of 0.76-3.0um is called refle...
The Application of Zoom Lenses
Ⅰ. The selection principle of the zoom lensesThe maximum imaging circle size of the lens should not be less than the imaging specification of the camera chip, that is to say, 1/2 lens can be used wit...
The Basics of Bandpass Filters
Bandpass filters are used to transmit the required wavelength range and cut off the unwanted wavelength range. Their design is essentially a thin film formed by vacuum deposition technology, which con...
Basic Concepts and Parameters of Optical Filters
1. The basic concept of optical filterAn optical filter is simply an optical device used to selectively filter the required radiation band. The substrates are mostly optical materials such as white gl...
Classifications of Filters
Although there are many types of filters, they all have the same basic function: transmit light of a specific wavelength or color range while preventing the remaining wavelengths from passing through....

Tips on Selecting The Bandpass Filter
1. What is Bandpass Filter?Bandpass Filter is optical filter that passes one or more specified wavelength bands while blocking other wavelength bands. Bandpass Filter refers to wavelength ranges and i...
What Are the Effects of Fisheye Lens?
Ⅰ. What are fisheye lenses?A fisheye lens is a type of super wide-angle lens that aims to view as far as the human eye can perceive, if not farther. However, there is a significant difference, becaus...
Understanding the Methods for Cleaning Singlet Lens
We all know that Singlet Lens is very important for SLR cameras, and the imaging quality of photos is determined by the lens. When we go out to travel, we always take our SLR camera with us. Over time...
