INTRODUCTION
1.1 INSTRUMENT DESCRIPTION
The Model 6300 is a microprocessor controlled Visible Range Spectrophotometer covering the wave-
length range of 320 to 950nm with a 10nm bandwidth. The monochromator is of a modified Czerny Turner
design, incorporating a stepper motor driven 1200 lines/mm holographic diffraction grating and featuring
automatic second order response suppression. The 6300 has full interfacing capability for Analogue output
and serial (RS232) interfacing. The optical system is independantly housed and isolated with lenses to give
maximum protection from environmental contamination. Combined with a mechanically rigid structure, the
6300 provides a system with fast warm-up, low drift and high reliability.
