However, when presented to Kiatichai Faksri of Khon Kaen University in Thailand, he commended its single-tube quantification accuracy but noted difficulties switching excitation lasers and filters to quantify different materials. Commercial spectrophotometers utilize white light lasers, which cover the full visible spectrum, in conjunction with diffraction gratings to choose the optimal excitation wavelength for a given biological sample (Dondelinger, 2011). However, these lasers often exceed $3,000, as they combine an array of laser wavelengths into a single compressed laser. Additionally, the many moving parts make these systems prone to breaking, while increasing size and bulkiness. A cost-effective alternative is a 5000K LED emitting the full 350-750 nm visible spectrum (Liu et al., 2018). To test our LED, we excited green fluorescein dyes at 30°, 45°, and 60°, finding 45° optimal for fluorescence visualization with minimal glare (Fig. 3). Additionally, we coated the inside of Micro-Q Pro with Musou Black Paint, which absorbs 99% of visible light, to eliminate excess ambient light for clearer imaging (Chu, 2019). - + <Image src="https://static.igem.wiki/teams/4683/wiki/measurement/fig3-2.png" caption="Figure 3.
