Q: Aren’t LIDARS big and expensive?2020-05-25T17:45:38+01:00

A: Most LIDAR companies would like you to think so. LIDARs have been in operation in Universities and Research laboratories almost as long as lasers have been around. These setups were very large and expensive. Most LIDAR companies are still building these kinds of products. At ISI we are always looking at the best of the new technological developments to ensure all of our products are as small and low cost as possible.

Q: Aren’t lasers dangerous?2020-05-25T17:45:13+01:00

A: Like most pieces of industrial equipment lasers can be dangerous if used in a dangerous manner. Use of lasers can be very safe if the correct design and expertise is applied. This is what we at ISI can provide, ensuring that any laser-based solutions we supply will not present a danger to employees, equipment or the public.

Q: Can a LIDAR do what I want?2020-05-25T17:44:47+01:00

A: Most LIDARs today are Laser rangefinders, such as those used by surveyors and estate agents. These can measure distances accurately. At ISI we specialise in more innovative uses of LIDARS, using them to measure pollution, process leaks, surface profiles and identification of molecules, both in gases and as liquids. We also use them to measure distances very accurately, but dramatically better than the everyday versions.

Q: What is a LIDAR?2020-05-25T17:42:29+01:00

A: LIDAR stands for LIght Detection And Ranging. It is sometimes known as LADAR (LAser Detection and Ranging). In essence it can be thought of as a Laser radar, but the only describes a fraction of a LIDAR’s capabilities.

Q: What is a high etendue / high throughput spectrometer2021-02-01T11:20:37+00:00

A: Most spectrometer designs currently available today require a slit to produce high resolution spectroscopy results. This slit is required due to the etendue or the solid angle area product that can be accommodated by the instrument.  This limits the throughput of the instrument or the amount of light that can be passed through the device. This slit can result in more than 95 % of the light being thrown away by the instrument, however as this fact is a constant this is not taken into account in the final instrument transmission specifications. ISI high throughput spectrometer and Raman spectrometer does not require a slit and can accept all the light from a 1 mm diameter 0.22 NA optical fibre, greatly increasing sensitivity.
