TL;DR: In this paper, a calibration lamp system for an astroobservation spectrometer is described, which is characterized in that the structure of the system is as follows: a color temperature filter, a semi-transparent semi-reflection mirror, a first group of lenses, a piece of frosted glass, and a second group lenses are successively arranged at an optical axis of a white-light lamp source.

TL;DR: In this article, aureola with high-accuracy flexible localization system is used to work of straining through the sheave system by driving system, its characterized in that, driving system and the driving method who strains between the aureolas are: driving system passes through the motor reduction gear and drives synchronous pulley I and synchronous pulpley II rotation, adopt synchronous Pulley power transmission between this pulleyI and the pulley II, constitute flexible power transmission, it is rotatory that this pulleys II drives sheave roller crank, stirs the

TL;DR: In this paper, an astronomical telescope starlight and calibration light coupling device and inputs starlight or calibration light to a spectrometer through a fiber is described. But the device is simple in an adjusting method, existing adjusting precision is not influenced when locking is carried out after adjustment, and a locking mode is reliable.

TL;DR: In this paper, a multichannel slit rotating switching device for a multi-target optical fiber spectrometer is described, which consists of an incident slit, an optical fiber, a slit switching system and a slit positioning clamping system.
