SOPHIA相机的关键特性包括:
“Over the past 35 years, Princeton Instruments has produced iconic cameras, spectrometers, and software — advanced scientific tools utilized by leading researchers and Nobel laureates around the world. SOPHIA extends this lineage of innovation. With ArcTec cooling technology, brand-new readout electronics, and a USB 3.0 interface all integrated via our acclaimed LightField software, we believe no other scientific-grade low-light detector can match SOPHIA’s performance and ease of use.”
- Ravi Guntupalli, VP Sales & Marketing, Princeton Instruments
SOPHIA的 30.7mmX30.7mm (2k X 2k)光敏芯片采用了15µm X 15µm 的像素,比常规的 13.5µm X 13.5µm 像素提高了23%的采光能力。SOPHIA不仅每个像素的光采集能力更强,其噪声也更弱了。全新的ArcTec制冷技术无需外部液冷器,极大降低了CCD的暗电流噪声。eXcelon芯片技术增加的频谱响应,减弱了近红外的干涉条纹,进一步提升了系统的信噪比.

Fluorescence, Phosphorescence, and Photoluminescence Spectroscopy
Fluorescence, phosphorescence and photoluminescence occur when a sample is excited by absorbing photons and then emits them with a decay time that is characteristic of the sample environment.
Astronomical Imaging
Astronomical imaging can be broadly divided into two categories: (1) steady-state imaging, in which long exposures are required to capture ultra-low-light-level objects, and (2) time-resolved photometry, in which integration times range from milliseconds to a few seconds.
Bose-Einstein Condensate
Bose-Einstein condensate (BEC) can be regarded as matter made from matter waves. It is formed when a gas composed of a certain kind of particles, referred to as “bosonic” particles, is cooled very close to absolute zero.
