PIXIS 成像型与光谱型相机

行业标准，高性能CCD相机

PIXIS系列相机是集成度高，低噪声设计的科学成像/光谱相机，响应范围从紫外到近红外。

结合PI特有的XP制冷技术，PIXIS是市场上特有的一款提供全金属真空封存，深度制冷的科研级CCD相机。真空质量终生质保。

高量子效率，超低噪声电子电路，使得PIXIS成为高要求的低光实验中理想的选择，例如：拉曼光谱，波什-爱因斯坦凝聚态（BEC），太阳能器件检测，荧光实验等等。

PIXIS相机可以选择eXcelon镀膜技术，增加其敏感度同时抑制近红外波段的干涉现象。

PIXIS相机具有以下特点:

• 支持不同芯片尺寸

• 频谱响应从~ 180nm至~1100nm （紫外到近红外）波段，更有eXcelon抗干涉技术eXcelon technology。

• 独特的全金属真空封存技术

Sensor Types:

Princeton Instruments' proprietary eXcelon process increases detector sensitivity in the blue and NIR while suppressing etalon interference fringes.

B/I DD (Back-illuminated deep depletion) sensors have up to 95% QE in the NIR with minimal etaloning.

B/I (Back-illuminated) sensors have up to 95% QE in the visible but are subject to etaloning in the NIR.

BUV (Enhanced UV) sensors offer the highest UV sensitivity with moderate visible sensitivity.

F/I (Front-illuminated) CCD sensors offer economical performance from ~400-1000 nm with up to ~50% QE and negligible etaloning. Open Electrode architecture improves QE by reducing the area of the electrodes.

Pixel Size:

All PIXIS cameras offer 100% fill factors

Larger pixels offer higher well capacity

Smaller pixels offer higher spatial resolution in some cases; for more information, see hyperlink to IsoPlane page

Peak QE:

Maximum values of quantum efficiency (QE) are shown at 25° C.

Tip-Enhanced Raman Spectroscopy

TERS - Tip-Enhanced Raman spectroscopy

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.

General Raman

The most common application of Raman spectroscopy involves the vibrational energy levels of a molecule. Incident laser light in the UV, visible or NIR, is scattered from molecular vibrational modes.

Surface-Enhanced Raman Spectroscopy

SERS - Surface-enhanced Raman spectroscopy

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.

Coherent Anti-Stokes Raman Spectroscopy

Coherent Anti-Stokes Raman spectroscopy (CARS) a type of non-linear Raman spectroscopy. Instead of the traditional single laser, two very strong collinear lasers irradiate a sample.

Stimulated Raman Scattering

Stimulated Raman scattering takes place when an excess of Stokes photons that were previously generated by normal Raman scattering are present or are deliberately added to the excitation beam.

Micro-Computed Tomography

Micro Computer Tomography is a unique technique for the noninvasive, nondestructive 3D characterization of materials down to a micrometer scale.
