Detail Produk "Alpha-1000 Visible Spectrophotometer"

The Alpha-1000 is a single beam spectrophotometer, which is designed to meet the needs of both students and instructors. Its digital display, easy operation, and wavelength range of 400 nm to 1000 nm makes this unit ideal for spectrophotometric experiments in the visible wavelength region of the electromagnetic spectrum.

The spectrophotometer consists of five parts:

Light Source (Halogen lamp) to supply the light
A Monochromator to isolate the wavelength of interest and eliminate the unwanted second order radiation
A Sample Compartment to accommodate the sample solution
A Detector to receive and convert the transmitted light to an electrical signal
A Digital Display to show absorbency and transmittance
In the spectrophotometer, light from the Halogen Lamp is focused on the entrance slit of the Monochromator where the collimating mirror directs the beam onto the grating. The grating disperses the light beam to produce the spectrum, a portion of which is focused on the exit slit of the Monochromator by a collimating mirror. From here, the beam is passed to a Sample Compartment through one of the filters, which helps to eliminate unwanted second order radiation from the diffraction grating. Upon leaving the Sample Compartment, the beam is passed to the silicon photodiode Detector and causes the Detector to produce an electrical signal that is shown on the Digital Display window.
