In the high-end fields such as short-wave infrared detection, near-infrared spectroscopy analysis, laser detection, and optical communication research and development, indium gallium arsenide (InGaAs) detectors have become the mainstream core components of detectors due to their wide spectral coverage, high quantum efficiency, room-temperature stable operation, and high-speed low-noise characteristics. However, whether the high-precision performance of the detector can be fully utilized completely depends on the precise control of the pre-optical path - even a slight deviation of the optical path, aperture error, or spot distortion can lead to signal distortion, decreased signal-to-noise ratio, and deviation in detection data, causing the precise detection to fail. The slit, as the core component of the optical path, its accuracy, stability, and adaptability directly determine the final detection level of the InGaAs detector system.

Traditional manual slit adjustment is rough, has poor symmetry, and low repeatability. Manual fine-tuning is prone to causing optical path deviations, which cannot match the micrometer-level and highly sensitive detection requirements of InGaAs detectors and are difficult to adapt to automated and high-precision infrared experiments and industrial detection scenarios. The electrically operated double-opening slit is specially designed for high-end optoelectronic detection scenarios, precisely adapting to the working characteristics of InGaAs detectors, with intelligent and precise optical path control capabilities to maximize the release of detector detection performance, becoming the golden complementary solution for short-wave infrared detection, spectral research, and precise optoelectronic detection.

Bidirectional symmetrical opening and closing, suitable for infrared optical paths, eliminating detector signal distortion

InGaAs detectors have extremely high requirements for the uniformity of the incident light spot and the center of the optical path. Eccentric light spots and distorted optical paths will directly reduce the quantum efficiency of the device and cause the detection data to drift. This electrically operated double-opening slit is equipped with a blade bidirectional synchronous opening structure, with ultra-precise grinding of the blade edge, balanced opening and closing, and locking the optical path center in the middle throughout the process, completely solving the pain points of ordinary slits being single-sided offset and light spot deformation, and providing a regular, uniform, and undistorted incident light source for InGaAs detectors.

The equipment is equipped with a precise screw drive system to achieve continuous and stepless adjustment of the slit width from 0 to 25mm, achieving micrometer-level positioning accuracy, with extremely low repetitive positioning error. It can precisely match the detection requirements of the 800-1700nm standard short-wave infrared band and extended bands of InGaAs detectors, whether for capturing weak infrared signals with narrow slits or collecting wide-spectrum data with large apertures, it can accurately calibrate the optical path parameters, perfectly adapting to precise experimental scenarios relying on InGaAs detectors such as Raman spectroscopy, near-infrared Fourier spectroscopy, and infrared imaging. The built-in elastic blades and limit protection structure ensure smooth opening and closing without jamming or over-adjustment, long-term optical path stability at its peak, and ensuring the detector continues to output precise and stable detection data.

Intelligent electric control, matching the automation detection requirements of the detector

InGaAs detection systems are mostly used for batch detection, continuous spectral acquisition, and high-speed optical signal testing. The drawbacks of traditional manual slits, such as repeated calibration and high human error, seriously restrict the detection efficiency and data consistency. The electrically operated double-opening slit is equipped with high-performance stepper motors, a universal standard interface, and supports intelligent control by computer software, enabling remote electric slit adjustment, parameter memory, and one-click automatic reset, without the need for close-range manual fine-tuning.

The control response is fast and smooth, perfectly adapting to the high-speed detection and continuous operation mode of InGaAs detectors, significantly reducing the optical path errors caused by manual operation, and improving the testing efficiency and data repeatability of the entire optoelectronic detection system. Truly achieving automation and standardization of optical path control, adapting to high-frequency and high-precision InGaAs detector detection scenarios in universities, optoelectronic enterprises, semiconductor processes, and optical calibration, completely eliminating the industry pain points of traditional equipment's low efficiency and unstable accuracy.
