Alpha-1860 UV/Visible Spectrophotometer

The Alpha-1860 is a general purpose instrument designed to meet the needs of the conventional laboratory, They are ideal for various applications, such as: Chemistry, Biochemistry, Petro chemistry, Environmental Protection, Food and Beverage Labs, Water and Waste Water Labs and other fields of quality control and research.

The Alpha-1860 incorporates a 320×240 dot matrix LCD display for photometric results, easy operation and wavelength range of 190nm to 1100nm. The instruments are ideal for measurements in the visible and ultraviolet wavelength region of the electromagnetic spectrum.

The spectrophotometer consists of five parts:

• Halogen and deuterium lamp to supply the light
• A Monochromator to isolate the wavelength of interest and eliminate the unwanted 2nd order radiation
• A sample compartment to accommodate the sample solution
• A detector to receive the transmitted light and convert it to an electrical signal
• A digital display to indicate absorbance or transmittance. The block diagram below illustrates the relationship between these parts.

In your spectrophotometer, light from the 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 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 displayed on the digital display.

The Alpha-1860 incorporate an USB1.0 for connecting to a PC for the Application Software, and include a parallel port for the optional built-in thermal printer for Alpha-1860.
