  • Optosky ATP2000P has a low-noise, high-performance, and cost-effective. The sensor used 2048 pixel CCD responding from 200-1100 nm.
  • ATP2000P is ideal for fast-detect because of high A/D converter frequency and the high-speed data transmission. In the memory chip is available for some solid programmed algorithms that can improve the performance, such as wavelength calibration coefficient, linearity coefficient. It transfers spectrum to PC through USB 2.0 or RS232 interface. ATP2000P operates with a single +5VDC supply supplied from USB or duo-pin interface.
  • ATP2000P 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.

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.
