Xi'an MH Electronics And Technology Co., Ltd. is one of the leading manufacturers of high-purity GaAs Gen 3 image intensifier tubes in China. With over 20 years of experience in electro-optics R&D and manufacturing, our MHNV/MH raw tubes are fabricated in ultra-clean Class 100 environments. Utilizing proprietary high-vacuum chemical vapor deposition (CVD) for Gallium Arsenide (GaAs) photocathodes, we continuously expand our manufacturing scale, ensuring a Figure of Merit (FOM) of at least 1800 on Class C tubes (verified by laboratory photometric testing), with premium Class A professional-grade batches exceeding FOM 2170+.
MH Electronics boasts a comprehensive product portfolio of nearly 3,000 optoelectronic components and advanced thermal & low-light imaging systems. Our core product, the GaAs Image Intensifier Tube, has been exported to countries such as Switzerland, Singapore, Germany, and Poland, obtaining multiple rigorous quality certifications. The entire production process guarantees absolute vacuum integrity, structural safety, and high-gain low-light performance under extreme environmental conditions.

Are you looking for a reliable, high-performance, and compliant GaAs Gen 3 image intensifier tube to boost your low-light imaging device competitiveness in the global market? We use automated laser photometric test benches to calibrate and verify our tubes, guaranteeing a Signal-to-Noise Ratio (SNR) of up to 32 and resolution up to 68 lp/mm. Due to its advanced microchannel electronic multiplication and low equivalent background illumination (≤≤0.25 µlx), our IIT is ideal for professional goggles, aerial photography payloads, and long-range security surveillance. Furthermore, our ISO and CE certified production processes ensure your products meet global industrial and safety standards while keeping your procurement costs minimized.

Q: What is the difference between P43 and P45 phosphors?
A: P43 provides a classic bright green image, whereas P45 provides a white-and-black image that significantly reduces eye strain during long-term operations.
Q: Do you provide actual test sheets (data cards) for each tube?
A: Yes, every single tube is shipped with its unique, verified laboratory data card detailing its exact SNR, resolution, and gain.
Q: Is your tube auto-gated, and does it support manual gain?
A: Yes, we offer auto-gated power supply configurations as well as 3-pin manual gain control options to fit various housing architectures.
Q: How do you handle phosphor defects (spots)?
A: We strictly follow rigorous industrial standards for spot zone specifications. Zone 1 is guaranteed to be completely clean on all Class A and Class B tubes.
Q: Can I order a sample unit for testing?
A: Yes, sample evaluation units of Class A, B, or C can be prepared. Contact our sales department to discuss technical specifications and sample agreement details.
