Digital low-light vision
BSI CMOS sensors capture low levels of ambient light. Digital processing and OLED displays present the image data in monocular and binocular systems.
D2L / SPECTRONIGHT
Observation for changing light conditions.
Digital night vision, thermal imaging and image fusion: the SPECTRONIGHT D2L family includes handheld devices, monoculars, binocular fusion systems and panoramic goggles for professional observation.
OVERVIEW
What this system brings together.
From portable observation to helmet integration, the D2L family covers different form factors and viewing requirements. The D2L-31F combines digital low-light and thermal imaging; the D2L-18 provides a 103° horizontal panoramic field of view.
We help define the configuration, interfaces and evaluation steps for your project.
