Product Code: ATP2700
application
ATP2700 high-sensitivity micro-spectrometer is a high-sensitivity, high-transmittance micro-fiber spectrometer. It adopts a high-efficiency optical system design, which makes its sensitivity 3-4 times stronger than conventional fiber optic spectrometers. It adopts a large numerical aperture optical design, which can All photons in the optical fiber (numerical aperture 0.22) are accepted. This makes it especially suitable for the analysis of low-light signals, such as gas analysis Raman spectrometers, fluorescence spectrometers, etc.
ATP2700 adopts high-sensitivity linear CMOS. Optosky specially customized ultra-low noise CMOS signal processing circuit, which greatly reduces the noise of the sensor and obtains an excellent signal-to-noise ratio (about 2 times higher than that of similar competitors). Its sensor is a 2048-pixel CCD, and the frame rate of CCD signal acquisition can reach up to 4Kfps.
It outputs spectral data to PC via USB 2.0 or RS232 interface. ATP2700 works with +5VDC power supply provided by USB.
ATP2700 can also be equipped with other types of detectors, such as cooled detectors (ATP5700), cooled area array back-illuminated detectors (ATP5700P, ATP5700R), deep-cooled -70°C detectors (ATP5700DC), to obtain better performance.

How many topology structure of optical path for a spectrometer?
There are commonly divided into 4 types of optical path, including crossed C-T, M-shape C-T, concave grating optical path, transmittance grating opitcal path.
Crossed C-T: ATP2000P,ATP2002, ATP2400, ATP1010, ATP5020P, ATP5040, ATP6500
M-shape C-T: ATP3030, ATP3034, ATP3330/4 ATP5030, ATP5034, ATP5330/4
Concave grating: ATP4230, ATP4020, ATP4050, ATP4070
let's see the M-shape optical path looks like a number "3", so our models uses the 3rd number "3" to indicate M-shape optical path models.
In generally, topology structure can decide resolution, sensitivity, stray light, and size of a spectrometer.
Crossed C-T topology structure employs better sensitivity and compact size.
M-shape C-T employs higher resolution and better stray light.
Concave grating optical path employs high stray light.
Which modular spectrometer can replace Ocean Insight FLAME-S-VIS-NIR-ES?
Optosky ATP2000 have same performance as Ocean Insight FLAME-S-VIS-NIR-ES, with integration time 1ms-65s, 2048 pixels.
