In tjconstant/thor2: Thorlabs Optics and Equipment Curves

thor2

Optical response of various thorlab components for use in R

The main function is named thorlabs_filter() and will return the fractional transmission given the wavelength(s) of a named filter. For example:

thorlabs_filter(name = "FEL0450", wavelength_nm = 200:700)

Returns the transmission of a long-pass 450 nm cut-off filter in the range 200 nm to 700 nm.

To quickly see the data and fit for any filter use thorlabs_filter.plot().

To export a filter's function to the global enviroment (following the naming convention of functions from the orginal thor package), you can do the following:

thorlabs_filter.import("FES0650")
# Then just use,
FES0650(wavelength_nm = 500)
# as before

For backwards compatibility with thor (v1), the FEL0550, FEL0600 and FES550 filters are exported to to the global enviroment automatically when the package loads. The APD120A2 photodetetor is also avaliable.

To Do

• Abstract functions further to automatically deal with parameters other than wavelength / transmission
