| Dec 21, 2017 at 14:55 | comment | added | Kapil Singh Rawat | Problem with grating is I'm not able to get enough light at the detection end. Even if I do this I also need to replace photo-diode with other detection thing like photo-diode array. Is it possible to get 10nm to 20nm wavelength step difference in grating. | |
