Optical Filters

Most commonly used fluorophores and alternatives

In this table listing commonly used fluorophore from Shorter wavelength to Longer wavelength. You can find: The emission and excitation wavelength and Color The commerical alterantive dye

Absorption in Optical Filters

Some filter material has properties that “capture” specific wavelengths. When light hits these molecules: For absorbed wavelengths: Photons (light particles) match the energy gaps in the material → energy gets...

Reflection in Optical Filter

Each dielectric layer is engineered so light reflecting off different layers travels paths that either: Constructively interfere (waves add up) for wavelengths the filter reflects (so they bounce back, not transmit). Destructively interfere (waves...

FAQs

What is the role of the Dichroic Filter in directing the light source?

What is a Dichroic Filter? A Dichroic Filter (sometimes called a dichroic mirror) is a highly precise piece of optical glass used to control light. Instead of just changing the...

Can I excite multiple fluorophores simultaneously with one light source?

Yes, it is entirely possible to excite more than one fluorophore at the same time using just one light source. This is a very common technique in biology and chemistry...

Does the light source heat impact fluorophore performance?

What is a Fluorophore? Imagine a tiny, microscopic glow-in-the-dark sticker. In biology and chemistry, scientists use molecules called fluorophores to act like these stickers. When you shine a specific color...

How do "Laser Clean-up Filters" protect the fluorophore signal?

Introduction: The Problem with "Perfect" Lasers When we think of a laser, we usually picture a beam of light that is exactly one perfectly pure color (a single wavelength). However,...

Why use a broad-spectrum lamp if a fluorophore only needs one color?

Introduction: The Single-Color Puzzle If you want to make a specific fluorescent dye (a fluorophore) glow, you usually only need one very specific color of light to "excite" it. For...

What is the benefit of using a laser as a light source for a fluorophore?

What are Fluorophores and Lasers? To understand why lasers are so useful, it helps to understand what a fluorophore is. Imagine a fluorophore as a microscopic glow-in-the-dark dye. When you...
