Support app for RX labs
May find use in RX ophtalmological labs which produce perscription lenses out of semi-finished blanks using free-form or conventional technology. An optician can use the app to calculate the true curve of a semi-finished blank based on the measurement of a comparator, whoose 0-value is set to be a flat surface. This is especially valuable when different blanks show minor variations on a per unit basis or when the distributor fails to supply a detailed table with measurements for their products.
- Measure the convex surface of the semi-finish. Input the data.
- Choose the index of refraction (based on material used)
- Correct for diopter power (optional)
- Click calculate
In order to use the app run the command npm run make
and use the distributable file in the out/ directory of the app
Disclaimer --Project for work This is an app I made for myself and a small set of colleagues at the company I work in. It is specific to our work environment - the machines, software and products that we use and it may NOT be useful to everyone. Please note that the coefficient I use to make measurements in this app are based on work practices in our lab and are not guaranteed to work outside of it.
