In order to improve the measurement accuracy of optical detection instruments, temperature control circuits for narrow band-pass filters are given, and the error analysis is applied to temperature control circuits.The principle of a temperature measurement circuit is studied and the method of a driver circuit is described. A variety of influencing factors of temperature control accuracy are discussed. Moreover, for these error factors, improvement measures are given to reduce the nonlinear error. Finally, circuit parameter error is quantified to propose a calculation method for margin of error in a temperature control system.

Figure 1 shows the design of a specimen stage used for the in situ observation of phase transformations in the temperature range between ambient and −160°C. The design has the following features a high degree of specimen stability during tilting linear tilt actuation about two orthogonal axes for accurate control of tilt angle read-out high angle tilt range for stereo work and habit plane determination simple, robust construction temperature control of better than ±0.5°C minimum thermal drift and transmission of vibration from the cooling system.
