Learn how ERDI develops, manufactures and supports laser sources, rangefinder modules and ranging and designation hardware before comparing individual models.
ERDI TECH develops laser sources, compact rangefinder modules and 1064 nm ranging and designation hardware for OEM integration. Optical design, coatings, electronics, mechanics, firmware and verification are coordinated around the finished system.
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 coordinates the transmitter, receiver, timing, power, mechanics and protocol as one integration problem. Recommendations are tied to stated test conditions and model-level documentation.
How ERDI worksTarget, range, accuracy, environment and host limits.
Wavelength, optical architecture, SWaP and timing.
Mechanics, power, protocol, trigger and thermal path.
Assembly and performance against agreed conditions.
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.
