Rancang Bangun Spektrofotometer Cahaya Tampak Menggunakan Motor Stepper Resol…

UV-Vis spectrophotometers have been used widely and are commercially available. However, the weakness of the technique is that the price isrelatively expensive. Therefore, low-cost analytical instrument with high resolution are needed, especially visible light spectrophotometers. This research was carried out with a working principle that resembles a visible light spectrophotometer using simple…
