A double beam spectrophotometer is one of the two basic types of spectrophotometer in use currently (the other type being the single beam spectrophotometer). Spectrophotometers are devices that measure the wavelength distribution of light.

These instruments are available in many shapes, configurations and sizes. A double beam instrument compares the light intensity between two light paths by splitting the light source into two separate beams. The splitting of the beam is accomplished either statically using a partially transmitting mirror or through attenuation of the beams optical devices.

One beam is used to illuminate the reference standard, while the other illuminates the sample. The instrument measures the amount of light of a specific wavelength absorbed by an analyte in a gas or liquid sample. Typically, the two beams of a double beam spectrophotometer are combined before they reach a single monochromator, but in some cases two monochromators are used. Depending on the wavelength being studies, an electrically powered ultraviolet, visible or infrared lamp can be used. A single beam spectrophotometer measures the relative light intensity of the beam before and after a test sample is introduced.

The comparison measurements from double beam instruments are easier make and more stable but single beam instruments still are useful for certain applications, having a larger dynamic range and being optically simpler as well as more compact.

Historically, spectrophotometers use a monochromator containing a diffraction grating to produce the analytical light spectrum, though some use arrays of photo sensors instead. Still other spectrophotometers that use a Fourier transform technique to acquire spectral information more quickly, a technique called Fourier Transform InfraRed.

A double beam spectrophotometer or single beam spectrophotometer quantitatively compares the fraction of light that passes through a reference solution and a test solution. Light from the source lamp is passed through a monochromator, diffracting the light into a "rainbow" of wavelengths. The outputs are narrow bandwidths of this diffracted spectrum. Discrete frequencies are transmitted through the test sample. Then the intensity of the transmitted light is measured with a photodiode or other brightness sensor. The transmittance value for this wavelength is then compared with the transmission through a reference sample.

Spectrophotometry routines consist of shining a light source into a monochromator. A particular output wavelength is then selected and beamed at the sample. The photodetector behind the sample responds to the light stimulus and outputs an analog electronic current which is converted to a usable format. The numbers are either plotted or (as is now most commonly the case) fed into a computer for further analysis.

The main advantages of a double beam instrument over the single beam spectrophotometer are an improvement in the stability of the light source, detectors and associated electronic devices. The disadvantages include the precision required in recombining the beams prior to reaching the monochrometer, the quality of the mirrors and other optics (if used) and their coatings and the problems which can created by dust buildup on these devices.

These disadvantages can make the double beam instruments somewhat more difficult to maintain than single beam devices, though the results they can provide make them ideal for certain spectrophotometry applications.

Trout are a very enjoyable species of fish to spend your time trying to catch. In this article, I'm going to discuss some tips that should help you catch more trout. When I speak of trout, I'm referring to the basic trout species that can be found throughout the United States. These species would include: Rainbow, Brown, Brook, Cutthroat, and Bull Trout. Although there are variations in temperament, colors, and size within these groups of trout, the methods for trying to catch them are similar. Below are some general trout fishing tips to help you catch more of any or all of the species listed above, especially in river and stream situations.

Size Matters - When it comes to trout fishing, the size of your gear and bait matter. In most trout fishing situations, ultra light to light gear and bait is the way to go. Unless of course you happen to be fishing for the monster Great Lakes visiting Brown Trout of the Midwest, in which case heavier gear will be necessary. I personally use a 5 foot ultra light rod and ultra light reel spooled with four for almost all of my trout fishing, and catch very large trout on a setup just like this. As far as hooks, the biggest I use for trout fishing with live bait is size 10. When it comes to lures, small lures are what you want to use as well. I personally don't normally fish for trout with spinners and spoons that are bigger than ¼ ounce. And minnow-type plugs shouldn't exceed four inches long, in my opinion when fishing for trout.

Clothing Matters - In river and stream situations when the angler is wading in an attempt to catch fish, the color of your clothing matters. Loud colors or even plain white, stand out and the fish will be able to see you. I always wear drab colors to blend in with the background as much as possible. Trout in rivers and streams can become vary wary of anglers, so not standing out works to the anglers' advantage. Simply pick a t-shirt that's brown or grey. As apposed to bright red or bright white.

Smell Matters - I'm not talking about the kind of deodorant you use. I'm speaking of the scent on your hands. All varieties of trout have a very sensitive sense of smell and can detect unnatural odors. For example, if you smoke, when you're done with a cigarette your hands smell like an ashtray. This smell then transfers to whatever you touch (if you don't believe me, just ask a non smoker if this is the case.) Therefore, when you touch the bait or lure to attach it to your hook or line, that scent gets on your bait! This will cost you a ton of bites. In most situations a trout will "sniff" the bait before biting it. If it stinks like an ashtray, there will be no biting. I suggest both grabbing a handful of weeds or dirt and rubbing it in your hands periodically, just in case any unnatural scants are on your hands. This simple tip will result in more bites.

Presentation Matters - Trout are a very intelligent species of fish. Whatever bait you chose to use must be presented in the most natural way possible. This is especially true with live bait. You want your bait to look as natural as possible. This is why I use a set of pre-tied gang hooks, because they enable me to present my live bait in an amazingly natural way. With trout in a river or stream situation, presentation matters as much as any other single aspect.

If you begin using these tips, you will start catching more trout. Actually, all I can promise is that you will get more bites, the setting of the hook, and actually fighting the trout, are in your hands. These tips will definitely help you get more bites, which is really what we're all in search of, right?
