Why is the traditional filter detection method ineffective?
Optical filters are optical components that are active in all major optical devices and can selectively allow a particular band of light to pass through while “masking” other bands of light signals.No. 1. It plays an important role in a variety of optical applications, including microscopic imaging, spectroscopic testing, hyperspectral imaging techniques, industrial inspection, biochemical instruments and scientific research.
A variety of key performance indicators to ensure stability and reliability.
Optical filters have a number of key performance indicators, such as transmittance, cut-off wavelength, polarization, and spectral response curve. By measuring these performance indicators, the response of the filter to the spectrum and its operational performance can be evaluated to ensure its stability and reliability during use.
Conventional Filter Inspection Methods are Complicated and Inefficient
Conventional optical filter inspection methods usually use a grating monochromator, a spectrometer and a light source system. Before each test, inspectors need to manually adjust the slit of the grating monochromator or calibrate the exit light of the monochromator, and manually record the intensity of different wavelengths passing through the filters on the software, which increases the labor and time cost.
Conventional Filter Inspection Methods Have Low Detection Accuracy
Manual operation inevitably brings about operating errors, thus reducing the accuracy of single-wavelength output detection.
Honghong Automatic Tunable Light Source Inspection Solution
The system integrates a broadband white light source, an automatic wavelength selector and a high-resolution spectrometer to provide stable white light output and automatically adjust the output wavelength and bandwidth of the light source to quickly collect spectral data, significantly shorten the inspection time, and reduce the cost of quality control. At the same time, the system has extremely high accuracy and detection efficiency, and is suitable for spectral inspection of narrow-band and very narrow-band flux optical filters and all kinds of filters.

Fully Automatic Tunable Light Source Inspection System Test Process and Results
The overall system structure is shown in the figure, which consists of three parts: the light source input, the detection position and the detection output. The light source input consists of an ML light source and an automatic wavelength selector; the detection position holds different types of filters to be tested; and the detection output consists of a customized detection module and an ML spectrometer. The system detects narrow bandpass filters in the range of 540-600nm with a center wavelength of 580nm.

Set product introduction
The Honghong High Spectrum System consists of a high-power infrared light source, tunable wavelength selector, lens and short-wave infrared camera designed for high spectral imaging applications. The infrared light source in the system provides high power output in the 900-1700nm range, while the wavelength selector provides fast, accurate and high-resolution tuning, and the short-wave infrared camera captures the image signals to produce high-quality images as shown in Table 1.
For customers with high spectral imaging needs, we will use the fully automatic tuning wavelength selector FWS-Poly as the core equipment, according to the actual application scenarios, to provide more accurate, high-resolution customized high spectral imaging solutions. This system is suitable for scientific research, industrial inspection and other fields to meet complex imaging needs.
MT White Light Source
The Mighty Light (MT Light Source) is a multi-functional compact halogen incandescent light source that integrates halogen bulbs, power supply and control board to provide low-noise output.
The MT light source can be directly coupled to a microscope or integrated with a wavelength selector to obtain a tunable monochromatic beam for microscopy, spectroscopy, machine vision and spectral imaging applications.
FWS poly automatic wavelength selector
Honghong's fully automatic wavelength tuning selector consists of a wideband bandpass filter that rotates independently to convert the broadband light source into a combination of light waves of a specified wavelength and bandwidth, and a compensation plate that corrects for spot shifts caused by the two rotating filters.
The technology supports 3-15nm bandwidth and UV to NIR (255-1650nm) wavelength range adjustment, all controlled by software, and realizes high-precision single-wave output.
SP Spectrometer
Honghong SP Spectrometer series is capable of detecting light in the range of 200-1050nm with UV-enhanced coating, which is particularly sensitive to UV wavelengths and offers high-speed data acquisition, low dark noise and low stray light, and flexible optical input methods (slit or fiber optic).
The series consists of four models with signal-to-noise ratios of up to 1000:1, making them suitable for a wide range of spectroscopic inspection needs.
