Shyamal Majumdar’s light measuring Ikophot
An ikophot is a handheld meter made in the 1950’s by Zeiss Ikon in Stuttgart, Germany. My grandfather Shyamal Kumar Majumdar probably procured this in the 1960s from Fancy Market, Kidderpore, Kolkata. It has a bubble glass at the front that takes in the light, which then drives the meter needle. It is covered by a little black lid which can be removed while using the device.
