Products
LDT864 series image intensifier tube adopts double proximity focused electronic optical system and S25+photocathode with extended near-infrared response and magnification ratio of 1, The product has the func-ions of strong light source protection and polarity reversal protection, and has the advantages of small sizelight weight and low power consumption.
Class A
The flagship product of the series, which adopts optical reflection reduction technology, with photocathode sensitivity of over 1000μA/lm and FOM up to 1900, and features such as near-infrared enhancement and small halo to meet the needs of users in identifying targets under different environmental conditions.
Class B
The upgraded product of the series, its FOM more than 1600, using auto-gated power supply technology, with a wider dynamic range, can adapt to a variety of complex environment, in the case of changing external lighting conditions, to provide users with a more comfortable observation experience.
Class C
The basic product of the series, with technologies such as high-contrast optic fiber inverter and input enhancement, It can provide higher image resolution and signal-to-noise ratio with FOM 1400 or higher, rendering superior image quality in low light conditions.
