I did not apply any mark-up for design and development cost recovery because I would have made this instrument anyway for my own use, and I wanted to make the price as affordable as possible. If I start making them for sale, then I will have to find ways of making them more efficiently in order to recover those initial costs.
Just to clarify: The Price I worked out includes both the labour and the cost of materials.
Also no retail pricing applies because I do not intend to make them available for retail. At least initially I intend to make no more than a couple per year as I have commitments in the laser industry.
