Abstract

PURPOSE:To avoid deformation of a base due to a flat error of an inserted cover, by adopting a pillbox system for the cover and the base with a given allowance. CONSTITUTION:Optical components of a spectrophotometer are mounted on a base 7 and they are covered with a cover 42 to interrupt them with an external light. The cover 42 and a cover 46 are formed insertionable to the convex part of the base 7 by means of the vacuum forming technology. A stand 32 of a collimator mirror 18 is directly fitted to the base 7. A stand 40 is fitted with a motor 41 and a bearing of a sector mirror. The light and reference light transmitted through a sample are applied to a photomultiplier 29.
