'Standard' testing of non-pulsed IR sources such as small lasers and IR
optocoupler alignment in equipment involves a CCTV camera and a monitor.
Any other way is a waste of time (I am not talking about tiny reflective
or transmissive off the shelf sensors). The cheapest CCD and CMOS cameras
work great for this.
