Tungsten lamp effect: 750W, 1.000W, 1.200W, 2.000W, 2.500W lamp emulation for whites from 2.700K to 4200K (red shift and thermal delay)

And expanding upon that, why is light absorbed by a material if it is not reflected? Thinking about it like atomic emission spectra, the other light should pass through. I know this is not the case because these are molecules and have many more energy levels that single atoms, but in the case that all of the light is absorbed, why is only some of it reflected? What dictates whether light is absorbed or reflected?

Building on the superb MSL™ (Multi-Spectral Light) colour concept, and innovative TE™ technology, our static T11 Fresnel™ maintains the exceptional colour finesse of the phenomenally successful T-Series. With a fast, interchangeable front lens system, the T11 Fresnel™ offers absolute, cost-effective flexibility while delivering superb optical quality.

Light is absorbed if it is propagating in a material and that material has some particles in it that are able to absorb light at that particular wavelength and be promoted into a higher energy state. Particles here could be electrons, but they could also be things like phonons (quantized lattice vibrations).

Fresnel lightLED

In the case of specular reflection, the photons just propagate according to Maxwell's equations. A high conductivity material or a boundary between materials with different index of refraction causes a boundary condition that causes the light wave to reflect. There's no absorption of the photons involved.

A virtually controlled CCT range of 2.700K to 8.000K (extended range 1.800K – 10.000K), calibrated whites, and tungsten emulation gives precise control, while we ensure skin tones are perfectly rendered due to T11’s high TLCI and TM30-18 ratings and exceptional CRI of 95+.

Cpulse™ is a PWM (Pulse Width Modulation) control system for luminaires that allows you to select and fine-tune the LED driving frequency to ensure no flicker will be visible on any camera system.

Light is reflected if there is a difference in the index of refraction of the two materials, or if the second material is highly conductive (for example, metal).

Robe has included a dedicated +/- green control channel in fixtures that feature our MSL™ specific white TE™ source fixtures. This allows you to make the smallest changes of green content compared to the fixed levels produced by the specific filters on white source fixtures.

Robe will be exhibiting at the two and a half-day 2023 SHOWTECH entertainment expo next week, staged in Halls 1 and 3 at STATION in Berlin, one of the country’s most charismatic and unique event spaces right at the heart of the German capital adjacent to the world-famous Potsdamer Platz.

Utilizing the rapid-change front lens system, the T11 Fresnel™ quickly transforms into a Profile or PC fixture for total luminaire flexibility without the cost of separate generic purchases.

Robe lighting’s Epass™ provides Ethernet in/out connections with a pass-through switch that sustains Ethernet integrity when the fixture has no power to automatically maintain network connectivity.

So if there's a light beam impinging on a surface, to be absorbed it should first not be (completely) reflected at the surface, and then it is absorbed as it begins to propagate into the material.

Robe's MSL™ (Multi-Spectral Light) LED light engines are, specifically, designed to consistently deliver the highest quality light through the additive colour mixing method. The MSL spreads the emitted light equally throughout the Planck curve, thereby providing the widest possible colour gamut, while simultaneously delivering seamless full range CCT control.

Do the atoms within a material absorb the photons and re-emit them in the direction they came back from (similar to atomic emission spectra, but slightly different because this involves hybridization of orbitals), or for some other reason?
