ISO 14490-1:2005 specifies the test methods for the determination of the following basic characteristics of telescopic systems and observational telescopic instruments: angular magnification; entrance pupil diameter; exit pupil diameter and eye relief; angular field of view in the object space; angular field of view in the image space; angular field of view in the object space for spectacle wearers; collimation of the bundle of rays emergent from the eyepiece; image rotation; closest distance of observation.
Abstract
Overview
ISO 14490-1:2005 - "Optics and optical instruments - Test methods for telescopic systems - Part 1: Test methods for basic characteristics" - defines standardized test methods for measuring the fundamental optical and mechanical characteristics of telescopic systems and observational telescopic instruments. The standard covers measurement arrangements, procedures, result determination and required test reporting for key parameters used in design verification, quality control and performance specification.
Key topics and technical requirements
The standard specifies test methods for the following basic characteristics:
- Angular magnification - measured by comparing angular size of an object and its image using an angular test arrangement (collimator + measuring telescope or micrometer eyepiece). Measurement precision requirements and uncertainty limits are defined (uncertainty
