You medical laser needs periodic measurement to ensure it continues to operate at the desired output settings.
There are two ways to measure the internal laser of your medical device:
Hulk: large, thermal sensor to absorb the full laser power.
Spiderman: small sensor to sample the beam in-process.
As you might expect, each method comes with advantages and disadvantages.
We’ve all been there before.
Struggling to reduce the cost of the BOM, we try to do everything ourselves.
After all, you’re an engineer, aren’t you? You have your own staff of hardware and software engineers, mechanical engineers, physicists, and anyone else you might need.
So, if there’s a complex part that adds a significant cost to your BOM, you’ll try to cut corners. “Let’s see how we can design that ourselves,” you say…
Medical devices have to be accurate.
Often, there are regulations about how accurate the medical laser system must be. Whether there are regulations or not, the main concern is the health of the patient.
We must be absolutely sure the laser and system are calibrated and accurate, so they will heal the patience, instead of causing an unfortunate accident.
As you design the laser aspect of your medical device, there are a few things you should think about to make sure the laser measurement sensor will be accurate and will continue to remain as accurate as it should be.
You might not need something for months, but when you need it, you need it yesterday.
So the saying goes for start-ups, but I expect it holds true for all companies.
The problem is, you aren’t just buying off-the-shelf sensors and figuring out where to stick them into your medical device. You need a custom solution.
Custom solutions take time to design, by definition.
