This is the macro tube setup I custom macined for a Mitutoyo M-plan 10x apo infinity microscope objective lens when using a Raynox dcr-150 tube lens. The setup uses raynox mounted in reverse. The minimum tube lenght is 145mm and a maximum of about 205mm from sensor to front of tubelens.
Please have a look at my other channel if you like, here most of the time I`m using a combination of Loawa lenses to get the zooming effect: [ Ссылка ]
