After Joseph Nicéphore Niépce’s success, the world of photography moved forward quickly. Lots of different inventors and chemists turned their attention to creating better cameras and improved photographic chemicals. The biggest leap forward came in 1888 when George Eastman developed his first camera which he called “Kodak.” The Kodak was the first to capture pictures on rolls of photographic film, which produced better quality, longer-lasting images.

The majority of Panacol’s glass adhesives will cure under UV light or visible light. Adhesives that were specially adapted to cure under visible light are the perfect solution to bond UV blocked glass (such as VSG). Both our UV and visible light curable adhesives for glass bonding can be used with either monochromatic LED light sources or broad spectrum UV discharge lamps.

Early cameras were little more than dark boxes with a lens on one side. To take a photo, the lens would be uncovered, and the light that came into the camera was focused onto a plate that was coated with a chemical like silver chloride or silver iodide. The silver would change colour and capture the image that was coming through the lens.

Except, instead of using rolls of film made using light-sensitive silver halides, digital cameras have a sensor that’s made of silicon. A digital camera’s sensor has a grid of thousands of tiny “photosites” that are sensitive to light. You’ve probably heard photosites called by their more common name: pixels.

The newest cameras have sensors made up of millions of pixels. When you point your camera and snap an image, light streams through the lens and hits the sensor. The sensor absorbs photons, measures the colour and intensity of the light, and turns that information into a long string of numbers. To a computer, that long string of numbers is a set of instructions that tells it how to show the image, which is why you can transfer digital images to any camera, computer or smartphone and they always look the same!

A main field of application for adhesives in medical systems is needle bonding and syringe assembly – the bonding of stainless steel needles or cannulas into glass or plastic syringes.

Curing in fractions of a second, our Vitralit® glass adhesives reduce assembly time and lower total process costs. These adhesives ensure high strength bonding of glass to glass, glass to metal (typically to steel or aluminium), or glass to other dissimilar substrates, including polycarbonate and acrylic. These adhesives are ideal for flat glass, float glass, tempered glass, and most other glass compositions.

Panacol’s glass adhesives are used to bond optical assemblies, mirrors, hardware for glass shower enclosures, display cases, outdoor lighting, decorative bevels or bonding of electronic displays. Medical applications include the bonding of metal cannulae into glass syringes.

Bonding glass to glass, glass to metal or glass to polycarbonates can be challenging – not so with Panacol’s glass adhesives. As glass is transparent or translucent, UV curable adhesives are the best choice for ensuring a reliable,  permanent, and invisible bond.

The earliest cameras worked using a clever chemistry trick. Certain chemicals (like silver chloride) change colour when they’re exposed to light. In this case, silver chloride darkens when the light hits it, allowing a photographer to capture a black and white image.

The type of camera you’re more familiar with is the film camera. The first film cameras were developed in the early 1800s by French inventor Joseph Nicéphore Niépce. Building on earlier research that showed certain chemicals change colour when they’re exposed to light, Joseph was able to take the world’s first photograph in 1826.

Panacol’s Vitralit® glass adhesives are single component and solvent-free, easy to dispense and to handle. Many are available in multiple viscosity ranges, from water-like wicking grades to highly filled thixotropic gels. Vitralit® glass adhesives can be specifically matched to the unique requirements of the application. Selections can be made based on the adhesive’s optical clarity, refractive index, or resistance to environmental stresses including temperature and humidity. To minimize movement and stress in optics, Vitralit® adhesives are available with low CTE (coefficient of thermal expansion), low shrink during cure, and high Tg. For medical applications, Panacol possesses a variety of medical grade adhesives that are biocompatible and are resistant to common sterilization processes.

Camera

That’s right. The tiny little camera on the back of your phone is the result of more than 200 years of research and scientific developments! While humans have been using our own two hands to paint and draw for thousands of years, it was only in recent times that we figured out the science of taking photos.

With a history dating back thousands of years, cameras are one of our most important inventions. If you’re a budding photographer, chemist or filmmaker, the Street Science team would love to help you dive deeper into the topic! Our popular See the Light for Year 5s show is all about how light moves and is absorbed, and we guide students through the process of making light-sensitive bands that work much the same way as cameras.

How cameraWorks

These days, film cameras work on the same basic principles, but the technology has come a long way. Modern films use a group of chemicals called silver halides. Silver halides are light-sensitive crystals that change colour when exposed to light. On photographic film, silver halide crystals are coated in gelatin to protect them from being exposed to light and to make sure the photo doesn’t fade after it has been taken.

The very first type of camera was called a “camera obscura.” Unlike the camera on your phone, a camera obscura doesn’t snap a photo that you can print out and carry around. Instead, a camera obscura is a dark room with a small hole or lens in one wall. The light that streams through the lens projects an image of the outside world onto the wall across from it.
