SPEC STD / SPEC STD FL

​• Designed for Fluorescence measurements
​• Wavelength range: 300-1000 nm
​• 200 µm slit and collecting lens for maximum sensitivity
​• 600 grooves/mm grating blazed at 500 nm
​• Order sorting filters included
​• Gain control up to 500 levels

The SPEC STD FL spectrometer was specially designed to be an affordable option for fluorescence measurements, including a 200 µm slit and collecting lens, as standard, for maximum sensitivity. 

The detector uses the Sony 2048 pixels CCD Array with 200 µm pixel height. Also included, the SMA 905 connector for optical fiber and order sorting filter which removes higher order effects.

The SPEC STD FL offers great sensitivity allowing detection of 19.3 pM of Eosin in low picoMolar concentration when configured with Sarspec's LED Light Source with LED-495nm, the multipurpose cuvette holder and 1000 µm optical fiber (2 units) - images below.

It is also suitable for reflectance measurements of low reflection samples and its a flexible solution for users that have emitting sources with very low intensity.

These spectrometers due to it’s performace and price are ideal for educational purposes in Chemistry, Biology, and Pharmaceutical areas.
