  • Optosky ATP2000H UV-Vis spectrometer is a low-noise, high-performance, high flame speed(>2k fps). The sensor used 2048 pixel CCD responding from 200-1100 nm.
  • ATP2000H is perfect for fast detection attribute to its high A/D converter frequency and the high speed data transmission. In ATP2000H memory chip, some algorithms to improve the performance are programmed solidly, such as wavelength calibration coefficients, linearity coefficients. It output the spectrum data to PC through USB 2.0 or RS232 interface. ATP2000H operates with a single +5VDC supply supplied from USB or duo-pin interface.
  • ATP2000H has free SDK for customers self-developed, Optosky support C++, C#, Labview and Linux system SDK, which is very convenient for OEM customers to design solutions.

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.
