Next design of lab-style enclosure (posted here too). This one allows you to use the OPT101 photodiode with the CJMCU101 PCB board (widely offered on eBay); you can connect the 6F22 battery as a power supply and finally, use regular BNC connector for signal output. In contrast to old one this design is much advanced, so no more requires any glue, all details assembles by snap-on connections (click-clack assembly) and of course, the PCB make the diode mount in a more easy way. Thanks for any comment
