At NP-Optics, our commitment is to build high-performance, supremely reliable thermal imaging scopes. For any aiming system, absolute precision is non-negotiable. In the world of daytime optics, the optical collimator is the universal tool for ensuring this. Yet, a fundamental barrier exists for thermal scopes: infrared light cannot pass through a standard collimator’s objective lens, rendering this essential QA process useless.
Confronting this industry-wide challenge head-on, NP-Optics embarked on an in-house R&D mission. The result is our proprietary Multispectral Boresight Collimator. This advanced instrument can simultaneously process infrared, visible, and laser wavelengths, allowing it to precisely measure the alignment—or misalignment—between the thermal sensor core, the display reticle, and the objective lens.
How This Calibration System Defines Our Manufacturing:
- Assembly-Level Alignment: After initial assembly of the core, eyepiece, lens, and OLED display, the unit is placed in the collimator. Components are then minutely adjusted and secured, establishing a foundation of perfect alignment before final assembly.
- Final Inspection Verification: Post-assembly, every scope must return to the collimator for final QA. We enforce a stringent 15-pixel tolerance standard, ensuring the reticle center deviates from the true optical axis by no more than this limit.
- Reliability Re-verification: Qualified units then undergo a brutal shock test: 1000 cycles at 2Hz with 700G acceleration. After this simulation of extreme recoil and impact, the scope is tested a third time. It passes only if its boresight remains steadfastly within the 15-pixel tolerance.
Extended Precision: This system also calibrates integrated laser rangefinders, ensuring the laser dot coincides exactly with the on-screen aiming point, creating a unified “range-and-aim” system.
Every NP-Optics optical device passes through this multispectral calibration gauntlet. We believe exceptional thermal image quality is the starting point. Absolute aiming reliability, built on millimeter and pixel-level precision, is the ultimate promise of a professional tool. This is the accuracy we build into every scope.
