  MM-3 Multi Wavelegth Irradiation system


MM-3 Multi Wavelegth Irradiation system



The Model MM-3 is capable of irradiating multiple samples simultaneously ( for example, 11 pcs of rectangular cell 10mm x 10mm ) in each wavelength band of 220-520nm and 400-700nm.


Not only the solid samples but also liquid samples can be irradiated. Since either the irradiation time by the timer or the count number irradiation by the energy counter can be arbitrarily set, the total irradiation time to each sample and the total energy amount to each sample can be known and the wavelength dependence test on the sample can be performed in a short time.



It is possible to test deterioration dependence on wavelength for various samples ( you can see at which wavelength the sample will deteriorate).


■ The Model MM-3 can irradiate the sample in arbitrary wavelength range in the wavelength

rage of 220 ~ 700 nm.


(The wavelength band (width) that can be irradiated simultaneously is about 300 nm.)


■ White light (light which is not spectrally separated) can also be taken out (option )



■ It can irradiate any samples such as liquid samples (drinking water, eye drops, paint)  and solid

(cosmetics, tablets, film, plastic , rubber).
