Mini Micro Spectrometer
application
With 20 years of experience in developing fiber optic spectrometers, Optosky presents the next generation of high-performance ultra-thin fiber optic spectrometers: the ATP2400SH. The ATP2400SH is extremely small and lightweight. It features a built-in pulse xenon lamp driver circuit, a high-sensitivity linear CMOS detector, and a specially designed ultra-low noise CMOS signal processing circuit, significantly reducing sensor noise and achieving an excellent signal-to-noise ratio (approximately twice that of similar competitors). This improvement enhances the measurement reliability of the ATP2400SH, ensuring that the measurement results remain stable regardless of environmental temperature changes, reaching the industry's best standards.
The ATP2400SH can receive light input through an SMA905 fiber or free space and output the measured spectral data via a USB 2.0 or UART port. The ATP2400SH offers a very fast frame rate: USB 2.0 (2Kfps) and RJ-45 (4Kfps). It only requires a 5V DC power supply or USB power, making it very convenient for integrated use.

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.
