2 Introduction

2.1 Description

The M305 blackbody calibration source design achieves significant weight and size reduction

over the M300 with only minor sacrifices in specification and performance, making it an ideal

unit where portability is required or space is limited. The spherical cavity yields an emissivity of

0.995 over the temperature range of 100 °C to 1000 °C with an aperture of 25 mm. An integrally

mounted PID controller completes this versatile calibrator.
