Product selection begins with target reflectivity, specified range, accuracy, repetition rate, beam divergence, dimensions, power, communication and environment—not with a model name alone.
Pulsed erbium-glass and DPSS transmitters evaluated by pulse energy, beam quality, package, drive and thermal path.
Open platform →Compact OEM modules for UAV gimbals, handheld optics, EO/IR payloads and long-range observation systems.
Open platform →Short- and mid-range modules for industrial sensing, robotics, monitoring, night vision and portable instruments.
Open platform →System-level modules coordinated around energy, divergence, pointing, timing, thermal design and platform interface.
Open platform →ERDI provides current quality-system and product-compliance documentation during technical and commercial review. Applicability depends on the named legal entity, certificate scope, product, destination market and validity date.
Follow the same decision chain used in a serious OEM program: understand the physics, define the requirement, design and integrate the system, verify it, then manage the application lifecycle.
Time of flight, wavelength, pulse energy, beam divergence, receiver aperture, detector response and signal-to-noise.
