What is ISO 14490-5 about?
ISO 14490 is an International Standard on optics and photonics that aims to deliver telescopic systems that offer optimal precision and performance.
ISO 14490-5 is the fifth part of the multi-series of documents that specifies test methods for the determination of the transmittance of telescopic systems and telescopic observational instruments.
Who is ISO 14490-5 for?
ISO 14490-5 on telescopic systems is relevant to:
- Manufacturers of telescopic systems
- Manufacturers of optical instruments
- Arms and defence equipment manufacturers
- Regulatory bodies
Why should you use ISO 14490-5 ?
Telescopic sights, often called “scopes,” are small telescopes mounted on top of the firearm that help magnify the target to take accurate shots, even at longer ranges. However, these scopes have a lens coating that improve the transmission of light to reduce glare.
With ISO 14490-5, manufacturing the right telescopic systems with improved image for the user also helps increase eye relief- the distance between the scope and the user’s eye and scope. This prevents being hit in the eye by the recoil of the gun.
Improving the quality of telescopic systems and telescopic observational instruments by determining transmittance through test methods, can be achieved with ISO 14490-5.
Overall, ISO 14490-5 help the user in building a high-quality product that offer precision, and accuracy for optimal performance and avoid product failure and damages.
