Our Workhorses

Model- Shimadzu UV-NIR-3600

Description- UV-Vis-NIR spectrophotometer is an instrument for transmission and absorption measurements of powder, thin films, solid and liquid samples. Working range of the instrument is around 185 to 3300 nm

Funding- Department of Chemistry, IIT Bombay

Location: Room 370, Central Facility, Chemistry Building

Model- Horiba FluoroMax-4

Description- Spectrofluorometers (or fluorescence spectrophotometers) measure the fluorescence signature of an analyte in a sample based on its specific excitation and emission wavelengths. Typical work range of Fluoromax is around 250 to 800 nm

Model- DeltaFlex TCSPC, Horiba

Description- Mai Tai® Ti:Sapphire oscillator is used as an excitation source of this TCSPC setup. It has a fundamental emission wavelength of 800 nm with a repetition rate of 80 MHz. Second harmonic generation (SHG) and Sum frequency generation (SHF, mainly THG) give us an opportunity to excite our samples with any wavelength between 275 nm to 520 nm. Our TCSPC is equipped with a hybrid picosecond photon detector (HPPD).

Model- Microtime 200, PicoQuant

Description- It has a complete confocal system with a laser combining unit, inverted microscope body, and dual-channel detection unit. Diode lasers for multicolor excitation of 405, 440, 532 and 640 nm are available. Two parallel detection channels using application-optimized detection with single-photon avalanche diodes (SPADs) are equipped with the system. One can perform fluorescence lifetime imaging (FLIM), as well as fluorescence correlation spectroscopy (FCS) with this versatile setup of Microtime.
