Generally, TOF laser distance sensors are not suitable for measuring distances to anything transparent at the laser's wavelength.

Bouncing the laser beam at an angle may work, but the problem then is getting the bounced laser light back to the sensor, and doing the math to get the actual distance.

Strangely, success has been reported with a specific sensor, but I don't know how reproducible it will prove to be; I haven't tried.
