Q: Which are 4 best micro spectrometer applied to Raman spectrometer from Optosky store?
A: ATP2000P CMOS Cooled 0 degree, the cheapest cost, good performance-to-price rate
ATP5020 Cooled -5 degree, High performance cost less, super high resolution
ATP5020R cooled -10 degree,NIR response enhanced, integration time 6ms -30 mins
ATP6500 Cooled -20 degree, Super high SNR & Dynamic range, Integration time 10ms-1.3 hrs
Q: How to test the peformance of Raman spectrometer ATP5020R?
A: As the Silicon spectrum with 532nm Raman ATP5020R, the obvious Raman peak of Silicon reach to 2700, with smooth spectrum.
Q: Which detector used for the ATP5020P?
A: ATP5020P uses Hamamatsu s11850 with uv response enhanced
ATP5020R uses Hamamatsu s16011 with NIR response enhanced
Q: How to choose Optosky TE-cooled spectrometer series?
A: ATP5020P crossed C-T, Hamamatsu CCD cooled, higher sensitivity, SNR & dynamic range is higher than Maya.
ATP5030P M-shape C-T, higher resolution and low stray light, Hamamatsu CCD
ATP5030 (2048pixels) & ATP5034 (4096pixels) CMOS+TE-cooler, M-shape C-T, high resolution
ATP5330 (2048pixels) & ATP5334 (4096pixels) Thin, cooled CMOS+TE cooled, M-shape C-T, super high resolution
Q: How many types of 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, ATP6500
M-shape C-T: ATP3030, ATP3034, ATP3330/4 ATP5030, ATP5034, ATP5330/4
Concave grating: ATP4230, ATP4020, ATP4050, ATP4070
Q: What difference about crossed C-T and M-shape C-T?
A: 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.
