The human cornea and lens absorb 1535nm radiation before it strikes the retina. Because of this Class 1 eye-safe profile, transmitters can unleash significantly higher peak energy per nanosecond pulse without risking blindness to nearby personnel. That extra energy translates directly into link margin when punching through thick air. https://laserrangefinder.cc/guides/boresighting-a-laser-rangefinder-with-thermaldaylight-cameras monthly 0.5 2026-10-06 https://images.squarespace-cdn.com/content/v1/6a5847a253bfe7478aec9c10/65bf35a7-694d-4dfc-a9a2-ab7d9d810164/ScreenShot_2026-10-06_105607_291.png Guides - Boresighting a Laser Rangefinder with Thermal/Daylight Cameras: Methods & Tools - WhateThe Physics of Seeing Together: Coaxial Alignment EO/IR Payloads Every sensor mounted inside a stabilized turret operates within its own optical domain: Daylight cameras collect reflected ambient photons.

One may be rated against a large diffuse target in clear air. Another may be intended for a smaller target at a shorter distance. If the target and atmosphere are missing, the accuracy figure has far less meaning. https://laserrangefinder.cc/guides/laser-rangefinder-module-for-handheld-optics monthly 0.5 2026-09-18 https://images.squarespace-cdn.com/content/v1/6a5847a253bfe7478aec9c10/28aea7be-a708-443c-b104-11047e91ba11/e96a13f4-b184-4ff2-830a-910c034f6da0.png Guides - How to Select a Laser Rangefinder Module for Handheld Optics - Handheld equipment punishes excess. A few extra millimeters can interfere with a battery tray. Twenty grams in the wrong place can make binoculars feel nose-heavy. A high peak current can force you into a larger battery. Even a connector facing the wrong direction can turn a neat internal layout into a wiring headache. https://laserrangefinder.cc/guides/laser-rangefinder-beam-divergence monthly 0.5 2026-09-18 https://images.squarespace-cdn.com/content/v1/6a5847a253bfe7478aec9c10/7bb9d9f4-0545-4bc5-acf5-12149f535ebe/b8d072e2-5205-4d9e-b9a7-3ed8878ff194.png Guides - Laser Rangefinder Beam Divergence Explained: Spot Size at 1–20 km - Why Laser Rangefinder Beam Divergence Matters at Long Range A laser beam does not stay the same width from the transmitter to the target. It gradually expands as it travels. You can picture it as a very narrow cone. Close to the laser, the cone is small. A few kilometers away, its footprint becomes much wider. https://laserrangefinder.cc/guides/laser-rangefinder-module-into-an-eo-gimbal monthly 0.5 2026-09-18 https://images.squarespace-cdn.com/content/v1/6a5847a253bfe7478aec9c10/04de0b9f-4f73-4dcb-8c69-0bb9a2e72845/0a28e6cf-2fc0-419b-9d87-b57f5a6731ff.png Guides - How to Integrate a Laser Rangefinder Module into an EO Gimbal - Laser Rangefinder Module Integration Starts with the EO Payload Do not start by asking, “Should I buy the 8 km unit or the 12 km unit?” Start with the payload. https://laserrangefinder.cc/guides/ttl-vs-rs-422-for-laser-rangefinder-module monthly 0.5 2026-09-18 https://images.squarespace-cdn.com/content/v1/6a5847a253bfe7478aec9c10/5160fdfd-9aec-45b4-be99-a9cd1598a5eb/8b47a59e-34bb-4083-bec2-c1a4cd8004dc.png Guides - TTL vs RS-422 for Laser Rangefinder Module Integration - Laser Rangefinder TTL vs RS422: What Really Changes?

A large building at 6 km is not the same ranging task as a small dark object at 6 km.

Lower weight can also reduce the load on the gimbal motors, especially when the laser unit sits away from the center of rotation. This becomes even more important on airborne equipment. Saving 50 or 100 grams inside a payload may sound minor on a workbench, but that weight moves with the gimbal every second the aircraft is operating. https://laserrangefinder.cc/guides/laser-ranging-distance monthly 0.5 2026-09-18 https://images.squarespace-cdn.com/content/v1/6a5847a253bfe7478aec9c10/28aea7be-a708-443c-b104-11047e91ba11/e96a13f4-b184-4ff2-830a-910c034f6da0.png Guides - How Target Size, Reflectivity and Visibility Affect Laser Ranging Distance - Why Laser Rangefinder Target Reflectivity Changes Working Range The basic idea behind laser rangefinder target reflectivity is easy to understand. The module sends a laser pulse toward an object. Part of that optical energy reaches the target, part of it is returned, and the receiving optics collect a small portion of the returning light. https://laserrangefinder.cc/guides/how-to-select-a-320-km-laser-rangefinder-module monthly 0.5 2026-09-18 https://images.squarespace-cdn.com/content/v1/6a5847a253bfe7478aec9c10/1787192446995-Z6K0DP05FS7D4AJ4I86O/18e25569-b022-4b94-b960-55c87fedb475%281%29.png Guides - How to Select a 3–20 km Laser Rangefinder Module - Start with the Target You Need to Measure https://laserrangefinder.cc/home daily 1.0 2026-09-15 https://images.squarespace-cdn.com/content/v1/6a5847a253bfe7478aec9c10/816f3fca-34a6-4521-a79d-a887baddde49/838774e1-f9b9-4c2a-9fc6-f56ba0b7a334.png https://images.squarespace-cdn.com/content/v1/6a5847a253bfe7478aec9c10/111b312f-e8cc-4113-882f-26166f838968/652d7bad-cb00-43f6-b2fe-a748e35ab8001.png https://video.squarespace-cdn.com/content/v1/6a5847a253bfe7478aec9c10/008cc170-dfa4-4213-b864-d7823dc10766/playlist.m3u8 https://images.squarespace-cdn.com/content/v1/6a5847a253bfe7478aec9c10/5db1aa6e-3860-44e6-81b8-c5642024fe65/ScreenShot_2026-08-28_145821_578.png Home Home https://laserrangefinder.cc/about-us daily 0.75 2026-09-16 https://video.squarespace-cdn.com/content/v1/6a5847a253bfe7478aec9c10/008cc170-dfa4-4213-b864-d7823dc10766/playlist.m3u8 https://video.squarespace-cdn.com/content/v1/6a5847a253bfe7478aec9c10/008cc170-dfa4-4213-b864-d7823dc10766/thumbnail About us Huanxin Advanced Manufacturing & Class 10,000 Cleanroom Tour In-house optical cavity assembly, precision collimation, and environmental stress screening in our Changchun facility. https://laserrangefinder.cc/contact daily 0.75 2026-09-16 https://images.squarespace-cdn.com/content/v1/6a5847a253bfe7478aec9c10/5db1aa6e-3860-44e6-81b8-c5642024fe65/ScreenShot_2026-08-28_145821_578.png https://laserrangefinder.cc/3km-laser-rangefinder-module daily 0.75 2026-09-18 https://images.squarespace-cdn.com/content/v1/6a5847a253bfe7478aec9c10/c510ea2c-0c3f-4cfe-97a5-b475735fada7/0aed7ae7-5f45-467b-bfeb-f23b16664b2b.png https://laserrangefinder.cc/4km-laser-rangefinder-module daily 0.75 2026-09-18 https://images.squarespace-cdn.com/content/v1/6a5847a253bfe7478aec9c10/c510ea2c-0c3f-4cfe-97a5-b475735fada7/0aed7ae7-5f45-467b-bfeb-f23b16664b2b.png https://laserrangefinder.cc/6km-laser-rangefinder-module daily 0.75 2026-09-18 https://images.squarespace-cdn.com/content/v1/6a5847a253bfe7478aec9c10/c510ea2c-0c3f-4cfe-97a5-b475735fada7/0aed7ae7-5f45-467b-bfeb-f23b16664b2b.png https://laserrangefinder.cc/8km-laser-rangefinder-module daily 0.75 2026-09-18 https://images.squarespace-cdn.com/content/v1/6a5847a253bfe7478aec9c10/c510ea2c-0c3f-4cfe-97a5-b475735fada7/0aed7ae7-5f45-467b-bfeb-f23b16664b2b.png https://laserrangefinder.cc/12km-laser-rangefinder-module daily 0.75 2026-09-18 https://images.squarespace-cdn.com/content/v1/6a5847a253bfe7478aec9c10/c510ea2c-0c3f-4cfe-97a5-b475735fada7/0aed7ae7-5f45-467b-bfeb-f23b16664b2b.png https://laserrangefinder.cc/18km-laser-rangefinder-module daily 0.75 2026-09-18 https://images.squarespace-cdn.com/content/v1/6a5847a253bfe7478aec9c10/c510ea2c-0c3f-4cfe-97a5-b475735fada7/0aed7ae7-5f45-467b-bfeb-f23b16664b2b.png https://laserrangefinder.cc/20km-laser-rangefinder-module daily 0.75 2026-09-18 https://images.squarespace-cdn.com/content/v1/6a5847a253bfe7478aec9c10/c510ea2c-0c3f-4cfe-97a5-b475735fada7/0aed7ae7-5f45-467b-bfeb-f23b16664b2b.png https://laserrangefinder.cc/laser-rangefinder-module daily 0.75 2026-09-21 https://images.squarespace-cdn.com/content/v1/6a5847a253bfe7478aec9c10/c510ea2c-0c3f-4cfe-97a5-b475735fada7/0aed7ae7-5f45-467b-bfeb-f23b16664b2b.png https://laserrangefinder.cc/infrared-camera-module daily 0.75 2026-09-21 https://images.squarespace-cdn.com/content/v1/6a5847a253bfe7478aec9c10/ff65eb6d-7cd0-46a0-a074-dceab268676c/f5a1bebe-27b2-4bfd-b31f-fe0bfa8c4c6f.png
